1. Material Requirement Planning (MRP) |
1.1. Prerequisties for MRP |
Prerequisites Required for Entering a New MATERIAL REQUIREMENTS PLANNING:
After activation, "Material Requirements Planning" (MRP) access for each user must be setup in the ManEx System Security module. Users with “Supervisor Rights” will automatically have access.
Customer |
The Customer database must be established for Consigned part numbers. |
Part number in Item Master |
The part number must exist for a product or part. |
AVL |
The Manufacturer Names must exist when using the AVL in the Bill Of Materials. |
MRP Policies |
The Material Requirements Planning policies should exist for each product or part in Inventory Control. |
|
1.2. Introduction to MRP | The Material Requirements Planning (MRP) Module is the heart of Inventory Control. In ManEx, the Material Requirements Planning actions drive the user towards zero inventory on hand through the scheduling and rescheduling of open orders for products and parts.
When the Material Requirements Planning module runs, it accumulates all of the demands for products and parts, determines the available supply and recommends actions to be taken to meet the demand in the time required. (The attached Print Screens below <<BOM_Setup_MRP_Actions.docx>> displays an example of a BOM setup and how MRP gives the actions). The MRP module will also modify those recommendations by MRP policies established in the MRP Default Setup and in the Inventory Control Mgmt MRP Info for each part. MRP runs through a large number of tables and records to compile its calculations, and provides a snapshot of suggested actions at the same time it is ran. If users are changing things during this process it could definitely cause some strange outcome. To prevent this situation we strongly suggest that you use the Nightly MRP trigger. (Refer to Article #416 for more detail on trigger setup). Note: If you find the need to re-run MRP during the production work day then we suggest that you notify all departments that MRP is going to be ran and ask them to remain out of the system until the MRP run is complete. This will help assure that the most accurate MRP run is possible.
Run Scrap and Setup Scrap
If the Top Level Assembly has a run scrap and user would like MRP to calculate this run scrap in the demands for all parts on the BOM, it must be set up in the MRP Defalut Setup Screen.
If the user has scrap setup in the Inventory Control module and wants MRP to calculate it they must set it up in MRP Defalut Setup Screen. Note: If this field is changed it will update the setting in the Kit Default Setup and visa versa.
If the user wishes for the setup scrap qty’s to be included in the Kitting and MRP calculations, the Setup Stcrp box MUST be checked on the BOM. Checking this box along with a Standard Bld qty will tell the system to use Setup Scrap when calculating the standard cost. Note: The "Exclude Scrap & Setup Scrap" options within the Kitting Setup module will overwrite this option.
All lead times are calculated with the Production Calendar.
Policies may be used to determine whether the part is ordered on a Lot for Lot basis, on a Daily basis, Weekly, Semi-Monthly, Monthly, or quarterly basis. (Refer to Article #3032 for further detail on how the AVL Pref Codes affect MRP based on the Order Policy). The part may have minimum and multiple order quantities that influence the recommendations. Note: If the Order Policy happens to be left blank within the Inventory Control module, MRP will enforce the Order Policy of "Lot to Lot". If the Stock UoM is different than the Purchase UoM MRP will instruct you to Purchase the Stock qty UoM, not the Purchase UoM.
NOTE: When creating a PO for an item with different purchasing and stocking UoMs, be sure to enter the MRP suggestion into the Stocking qty field rather than the purchasing qty field. The system will automatically convert the stocking unit into the purchasing unit for the purchase order qty.
For example if the buyer is creating a PO for an item that is used by inches but sold by the foot, the user would enter qty of 24 into the stocking qty field and the PO would automatically convert it to 2 feet in the purchasing qty field. So the supplier deals in feet, but ManEx deals in inches. The conversion between the two are established in the Unit of Measure & Conversion module.
Article #3597 explains the process MRP goes through to optimize the On-Hand Inventory to Demands.
Buffer times for placing purchase orders and for placing work orders may be defined and included.
The Dock to Stock value (setup in the ABC types ) is taken into consideration for MRP leadtime calculations in the projected requirement of the receipt of purchased parts. (For more detail refer to Article #1469).
If a part has a Production Off-set time setup in the Bill of Materials , this is also taken into consideration for MRP leadtime calculations. (For more detail refer to Article #572).
The Material Requirements Planning module will run the Master Production Schedule generation automatically before running the Material Requirements Planning module.
ManEx Material Requirements Planning module may be run without logging users off the system. The work station used to run Material Requirements Planning should have at least 120MB available on the hard drive, and works best with 96MB memory or more.
A Material Requirements Planning regeneration creates time-phased material requirements at the part (component) level by netting demand from the Master Production Schedule (MPS), open Sales Orders, Internal orders, Shortages and open Work Orders (released but not picked) against supply from inventory, open purchase orders and Finished Goods.
The regeneration must also occur with demand synchronized: Master Production Schedule forecasted demand that has been consumed by Sales Orders should be relieved and Work Orders that are released but not picked should be picked or cancelled.
MRP Actions for Make/Phantom parts - If the actions originates from a higher level assembly for the Make/Phantom, then the MRP will display "Phantom" in the action section. This indicates to the user that there are no actions required and is listed so users can investigate where component actions are originating from. If the Make/Phantom is required directly for an Order itself, it will follow the same WO action rules as a regular Make product.
Planned Purchase Orders from previous demand that have been placed must be entered and/or firmed.
A Firm Planned Purchase Order tells MRP that the purchasing decision was intentional and MRP will NOT try to override.
Discrepant material should either be moved into Material Review Board or Inspection Hold for disposition. If Material Review Board or Held material is not to be looked at as available material for Material Requirements Planning purposes, it should be in a Non-nettable warehouse or inventory location. For example: (If parts are rejected in PO receiving the parts are dispositioned into the MRB warehouse (which is Non-nettable) so MRP is not seeing the qty in MRB but is seeing the open PO). Transactions must be current with the location of materials. WIP (Work In Process) shrinkages must be expressed as Work Order shortages in the system.
MRP is designed to calculate from the Kit Shortage and not from the Lead times once the parts have been pulled to the kit and the kit status is changed to "Kit in Process". Once the parts have been pulled to the kit, the systems is assuming that the shortages are needed by the WO due date, rather than the Prooduction lead time, so MRP then calculates using the due date of the WO as the date the materials must be on hand, MRP no longer takes the production lead time into consideration.
NOTE: The Re-Order Point/Qty fields have NO AFFECT on MRP at all. MRP will NOT consider these fields for any calculations (these fields have no connection with MRP). These fields are intended to control stock on overhead items. Print the "Inventory Material Reorder List" report (located in the Inventory Control module) to show items which have dropped below re-order point minimums.
MATERIAL REQUIREMENTS PLANNING PROCESS
Confirm status of system data for Material Requirements Planning validity
Updated Forecast and Master Schedule
Updated Item Master file data
Lead Times entered and up to date
Shrinkage factors current
Order policies set
Orders firmed as required
Independent Demand items identified
Inventories current
Receivings current
Safety Stocks appropriate
Bills of Material current and complete
Confirm system availability to run Material Requirements Planning
Timing good for snapshot of data
Transactions current
Set the parameters for running the Material Requirements Planning
Netable Inventory Locations flagged
Discrepant material dispositioned
Horizon set
Time fences set for change control
Bucket size and number set
When executed, the Material Requirements Planning Module takes a snap-shot of the demand for parts and assemblies (created by Sales Orders, Work Order Shortages, Forecasts) and compares it with supply (on-hand inventory, open Purchase Orders with scheduled qty, open Work Orders) in order to generate an Action List of planned new orders and changes to existing ones to meet demand. The comparison is done one day at a time using the make and/or buy parameters from the Item Master/Material Requirements Planning Information screen in Inventory Control Management.
The Parameters include:
· Order Policy
· Minimum Order Quantity
· Order Multiples
· Purchase Lead Time
· Kitting Lead Time
· Transit Days
· Pull In Days
· Push Out Days
If the AVL suggested to the PO actions is flagged as "DO NOT PURCHASE" MRP will give Release PO actions if there is a need for the part and the part will be displayed on the Create PO screen with the Mfgr and MPN fields blank. This should flag the user to further investigate and see that it is flagged as "DO NOT PURCHASE" and that they will need to either remove the flag or add additional AVL's to ful-fill the demands. Notice at the top there is a note that explains what the empty "MFGR" field means.
Sales Orders on Hold
When the Sales Order is on HOLD it does NOT drive MRP.
User does have the ability to turn off the function of the Sales order driving the demands for the MRP and just use the Work Order for buying components by checking the MRP on Hold box in the Sales Order module per line item or in the System Setup/Sales Order Default module.
If the MRP on Hold is checked in the SO module, MRP will instruct you to cancel all PO(s) you have open for the components needed for this SO.
If the MRP on Hold is checked in the SO module and you create a WO Manually, the MRP will tell you to cancel the WO since there is no SO demand. This can be solved one of two ways.
Use the MPS module (Forecast) or Open/Create Firm planned WO’s so the MRP will NOT keep instructing you to cancel the order.
This is a perfect solution for customer who wants to build products based on forecast or promised to maintain certain amount of FGI in inventory. The can use the MPS module to accomplish this and use the SO to ship products from FGI inventory.
MRP will consider any SO items for the demands unless marked as MRP on Hold. See Article #1244 for further information.
Check on Work Orders on either Admin or Production hold. Production Hold on a Work order will disallow movement of the parts. See Article #896 for more detail. MRP is checking work orders to be sure that they aren’t cancelled or closed. Everything else will be considered. MRP checks Sales Orders for OPEN status. Everything else is ignored. If the objective is to stop the shipment from the Sales Order, then in the Sales Order, the user may uncheck the “Sales Ack” box and then shipping won’t be able to initiate a Packing List.
Inventory Items Allocated
MRP does NOT distinguish between inventory items allocated to projects nor Purchase orders allocated to projects in the determination of the available supply (current and future). To do so would enormously complicate the MRP process. MRP WILL determine that the supply will meet the demand, whatever it is.
Should we have locked the requirements by project in MRP, then we could have the situation where we have unallocated inventory on hand, but since it's not for a specific product that requires it, MRP action could create an order action to buy more of the parts specifically for that project. This could result in an enormous amount of excess inventory. Since our objective in MRP is to drive to zero inventory, we do NOT want to ignore any available inventory that might satisfy demands. Conversely, when inventory is allocated to a specific project, and the demands created for another project are analyzed, the inventory on hand will be available to meet the other project demands, but also create the order actions to supply parts for the original project, if there are still demand requirements.
In the case of having just enough inventory on hand for a given Project (A), but there are new requirements for Project (B) that precede those for the same parts as project (A), MRP will assume that the inventory on hand will be used for Project (B) first, but get more parts to meet the later date of Project (A). As long as there is inventory available to meet every demand, it will be up to the user to reallocate inventory for the most urgent need.
If for some reason user has inventory that belongs to a specific customer and does not want MRP to consider it for any other customer they can change the inventory location to non-nettable.

This is a general part, product or item classification.
|
Part Type |
Type is a sub-classification of Part Class.
|
Description |
This is the field of descriptive data about the item. |
Part Source |
This field is hard coded in the system.BUY is for purchased parts and assemblies, MAKE for an item made in-house (assemblies and sub-assemblies) and PHANTOM for a number used to define a collection of items that does not exist as a separate assembly built on a Work Order (ship kits, upgrade packages, spares kits, etc.).
|
Material Requirements Planning Action List in Stock Units Of Measure:
The information listed in this section pertains to the highlighted part number in the main body above. To see the list for another part number, highlight the part number in the main body.
Note: Dates are calculated with the Production Calendar
Action |
Defines the Material Requirements Planning action to be taken for the highlighted part. There are several different actions that will appear depending on the part. For example if the Part is a Make/Phantom part and the action originates from a higher level assembly for the Phantom, MRP will display "PHANTOM" in this section and that will indicate to the user that there are no actions required but is listed so users can investigate where component actions are originating from. If the Make/Phantom is required directly for an order itself, it will now follow the same WO action rules as a regular Make Product would.
|
Balance Quantity |
The projected balance of inventory for the part selected. MRP will display the stock qty UOM.
|
New Quantity |
Displays the new quantity that the action requires. MRP will instruct you to Purchase the Stock qty UOM, not the Purchase UOM. The PO Module will display the UOM conversion (if applicable).
NOTE: When creating a PO for an item with different purchasing and stocking UoMs, be sure to enter the MRP suggestion into the Stocking qty field rather than the purchasing qty field. The system will automatically convert the stocking unit into the purchasing unit for the purchase order qty.
For Example: if the item has inches for Stock UoM and Feet for Purchasing UoM, and the MRP demand is 24 , the buyer would enter the qty of 24 into the stocking qty field and the PO would automatically convert it to 2 feet in the purchasing qty field. So the supplier deals in feet, but ManEx deals in inches. The conversion between the two are established in the Unit of Measure & Conversion module.
|
Original Date |
Displays the original (current) date of the existing action.
|
New Date |
Displays the new date that the action requires. For a buy part the New Date is arrived by subtracting the Kitting and Production Lead times setup for the Make part from the Sales Order Ship Date. For a Make part the New Date is the Sales Order Ship date. See Article #3064 for futher detail on how the Lead Times for a Level BOM are calculated. |
Days Late |
If the action date is earlier than the current date, the number of days late for the action is shown.
|
Date to Take Action |
This is the date by which the action listed must take place. Changing the leadtime of a Buy part will NOT change the due date, only the date to take action. For a Buy part this date is arrived by subtracting the Purchase Lead time from the New Date. For a Make part this date is arrived by subtracting the Kitting and Production Lead times from the New Date which is the Sales Order ship date.

To find one item, enter the part number in the 1st box, depress the return key and only that record will display. To view a series of items, enter the first and last part number of the series and all items numbered between will display. If you want All part numbers, leave this area blank.
If an incorrect part is entered into the range that does not exist within inventory, or there are no MRP records for the part entered user will receive the following message:
|
Buyer |
Select Buyer from the pull down menu. If you want ALL buyers, leave this area blank. Assigned Buyer will bring up all items assigned to that particular Inventory Buyer within the Inventory Control Management module. The Buyer assignment is setup in Part Class and Type System Setup Defaults or in the Inventory Control Management module/Item Master tab.
|
Part Class |
Select the Class from the pull down menu Part Class and/or Part Type will bring up only those items that match all entries made. If you want all Classes, leave this field blank. |
Part Type |
If you selected a Class, depressing on the down arrow will bring up a list of Types within that Class. Select the Part Type within the Class selected. If you want all of the Types within the Class, leave this field blank.
|
Find by Parent BOM |
The "Find by Parent BOM" is specific down to the Revision level. This filters MRP results per Selected Bill of Material. You MUST enter the exact part number and revision of the Parent BOM to get only the parts with actions per that BOM. Note: Only parts listed on the BOM with MRP action messages will be displayed. Parts with all actions from all sources will be shown on the screen if the part has actions from the entered BOM and other demands. A part may appear on the list even if there are not direct actions from the entered BOM if there are actions from the demands or such actions as Cancel PO/WO. There is no way to filter out the actions just to those actions resulting from demands from entered BOM. |
Rev |
Revision of Parent BOM. If applicable this MUST be entered to located the exact Parent BOM. The "Find by Parent BOM" is specific down to the Revision level. If the exact part number and revison of the Parent BOM is not correct user will receive the following message:
|
Parent Project |
If you select to find by a Project this is going to filter and display only parts that are assigned or associated to a project, but will display , ALL actions for that part , not just those that are associated with the project. If you had 3 actions for a part, each assigned to a different project, all three actions would be displayed when you Find by any of the three projects. |
Actions |
Select the action from the pull down. There are the various Material Requirements Planning actions, which the user may filter on such as: All Actions, All Purchase Order Actions, All Work Order Actions, Pull-Ins, Push-Outs, Release Purchase Orders, Release Work Orders, Cancel Purchase Orders, and Cancel Work Orders.
Note: When you filter by any of the selections, MRP will filter through the actions and display ONLY the parts that have an action that matches the selection. If it finds a match it will display all the the actions against that particular part.
For example: if you select to filter by "Release PO Actions". MRP will display ONLY the parts that have "Release PO Actions". If it finds a match it will still display all the other PO actions against that particular part. If it didn't users may overlook the fact that there are other PO actions for that particular part as well. However, it does filter out all the parts that "DO NOT" have any "Release PO Actions" against it.
|
Days |
Type in the number of days (from the current date), changes the Date Filter accordingly. This is a short-cut to the horizon date.
|
Date Filter |
The horizon date for the Material Requirements Planning actions. Parts with actions beyond this date are excluded from the report.

1.4.2. Add (Generate) A Material Requirements Planning (MRP) | Add (Run) a Material Requirements Planning
MRP runs through a large number of tables and records to compile its calculations, and provides a snapshot of suggested actions at the same time it is ran. If users are changing things during this process it could definitely cause some strange outcome. To prevent this situation we strongly suggest that you use the Nightly MRP trigger. (Refer to Article #416 for more detail on trigger setup).
If you find the need to re-run MRP during the production work day then we suggest that you notify all departments that MRP is going to be ran and ask them to remain out of the system until the MRP run is complete. This will help assure that the most accurate MRP run is possible. Then follow the procedure below:
Enter the SQLMANEX.EXE (within the ManEx root directory)
This action will then prompt the user for a password
|
|
The following screen will be displayed, select Material Planning/Material Requirements Planning (MRP), Material Requirements Planning (MRP) Module
|
|
The following Screen will be displayed:
To run a new Material Requirements Planning (MRP) manually, depress the Add action button (Generate MRP), and enter your password.
The run percentage will be displayed on the header as displayed below:
The time it takes MRP to run is dependent on a number of factors. Here is a list of items that affect the processing time:
the number of open Sales orders
the number of open Work orders
the number of open Purchase Orders
the complexity of the BOMs (levels)
the number of AVL's for parts
the number of active parts
Inventory safety stock, minimum orders, order multiples
A company with high annual sales but only a few open orders of all types and only a few simple BOMs will process quickly, a company with low annual sales, but with a large number of small orders, many BOMs and AVL's will take a long time to process.
We are not able to come up with an average time because there are too many conditions that affect the run time.
Once the MRP run is completed and was successful, user will receive the following message:
Depress the OK button. The Material Requirements Planning Date at the top right hand side of the screen will change.
If the MRP run was NOT successful due to AVL issues (missing, or exists but is marked as "Do Not Purchase and/or Kit, etc) the following message wil be displayed on screen indicating that MRP will NOT be able to continue until the BOM and/or part records have been correct. Then in addtion to the message an XLS file will be generated and placed in the ManEx Main Directory. This XLS file will contain the records that the user will need to review and address. If an XLS file is generated multiple times a day the system will add "_N" to the name of the XL file, where "N" is the dequence number. For example if MRP is run today three times without fixing a problem or a new problem is generated, the generated files will have names; badavls_2009.03.31_1.xls, badavls_2009.03.31_2.xls, badavls_2009.03.31_3.xls, unless one or all of the files were removed. The user will have the option of viewing the XL file now or later. NOTE: These XL files will need to be manually removed from the ManEx Main Directory.
If the user selects "No" the user will receive the following message and they may review the XL file placed in the ManEx Main Directory.
If user selects "Yes" an XL file (similar to the one shown below) will be displayed on screen and also placed in the ManEx Main Directory for later review:

1.4.4. Create POs from MRP Action List |
Enter the SQLMANEX.EXE (within the ManEx root directory)
This action will then prompt the user for a password
|
|
The following screen will be displayed, select Material Planning/Material Requirements Planning(MRP)/Material Requirements Planning (MRP)
|
|
The following screen will be displayed:
Note: To start creating POs from the MRP action list, make sure you have run MRP creating a fresh MRP action list, and user must have "ADD" rights to the PO module in Security setup.
Find an MRP record.
Highlight a part number of interest and depress the Create POs button in the bottom right hand corner, enter user password (user must have "ADD" rights to the PO module), and a list of Release PO suggestions based on the MRP filter that was applied and displayed within the MRP screen will appear. This will allow the buyers to auto created purchase order records based on what MRP is suggesting (mfgr, mfgr pn, etc...)
Note: ManEx does offer a pull down next to the Mfgr to select from listing only the approved AVL's for that BOM. Double clicking on MPN field will open a web browser session and navigate to Calculquote's web site Search.calculquote.com allowing you to use their search engine to find a matching part for quoting purposes. More info on Calculquote and how it integrates with ManexERP can be found here. Calculquote.com
Note: If the AVL suggested to the PO action is flagged as "DO NOT PURCHASE" MRP will give Release PO actions if there is a need for the part and the part will be displayed on the Create PO screen with the Mfgr and MPN fields blank. This should flag the user to further investigate and see that it is flagged as "DO NOT PURCHASE" and that they will need to either remove the flag or add additional AVL's to ful-fill the demands. Notice at the top there is a note that explains what the empty "MFGR" field means.
User may view records by selecting All Suppliers or only Suppliers assigned to the MPN in the ICM module. User may also use the Supplier filter to view records for one supplier at a time.
User may manually select the records to have POs created by placing a check in the box in the PO column. If no supplier is defaulted in the Preferred Supplier column from the ICM module, user may check item in the "x" column, select a supplier from the pull-down and receive the following message:
Depress "Yes" to continue and user will receive the following message:
Depress "Yes" and all the records that have the check box to the left of the "Preferred Supplier" column checked will be updated with the selected supplier.
The Cost Each is defaulted in based on the "Price Source" column (which is setup in the Purchase Setup module). The standard Material Price and the Target Price defaults in from the Inventory Control Mgmt module. The Contract Price is defaulted in from the Supplier Contract Mgmt module. The Quote Price is defaulted in from the Quotation & Estimating module. The quote MUST be approved. If the part is on more than one quote the system will use the price from the most recent quote. The Mfgr and Supplier listed on the Auto PO screen must match the Mfgr and Supplier that was selected on the quote. The Last Purchase Price and Last Purchase Price for a Supplier will only be listed if they are within the last 6 months, if not then zero dollars will be displayed. Manual Entry allows user to manually enter in a cost each.
NOTE: The Auto PO screen will only find existing parts entered in the "Material 1" screen. There is no way to identify parts from "Material 2" screen. There is no connection between part entered in the quote module "Material 2" screen and the part before it becomes an Inventory part in ManEx until after the "Transfer".
All coulmns in the grid are sortable. To sort on the specific column click the header of the column. By default the items are sorted by "Preferred Supplier" column (red color of the header indicates that the data sored by the values in the column). Part No and Rev columns are both sorted by Part No and Rev vaules. If the cursor is in Part No, Mfgr,or MPN columns and the user begins to type the information, the interactive search will be performed and the record pointer will be moved to the appropriate record.
Once user has selected the records, they can depress the "Create PO for Supplier" button and PO's will be created (one for each supplier).
Once the POs have been created an xls report will be generated in the Manex local directory for review. The XL file name is based on the user initials plus the date and time the file is created. For Example if the file created has a name "ONE-20070524-9-37.xls" "ONE" - this is the user's initials; "20070524" - is the date when file was created (YYYYMMDD); "9-37" is the time (Hours-Min) when file was created, so this file was created at 09:37 am.
User has the option of opening the created excel file by depressing Yes or No.
