When does the System use Stock UOM versus Purch UOM?
Question -  When does the System use Stock UOM versus Purch UOM?
 
Answer -    The system tracks the stocking UOM within inventory, kitting, MRP, etc.  The Purchase UOM is only used when creating the PO and accepting it into inventory.  Once the item is accepted into inventory it is converted over to stock UOM and from that point forward everything within the system is using the Stock 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 the 24 inches 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. 
 
Some examples may be:
 
Stocking Unit               Purchasing Unit            Conversion
1 Soda                        1 Six Pack                     1 to 6
Inches                        Feet                                1 to 12
Inches                        Centimeters                     1 to 2.54

And in some cases, some odd equivalents
Feet                              pounds                          based on how many pounds a foot of cable weighs. Cable would be used in the factory in feet, but is purchased by weight.
Ounce                           small bottle                   distributor may sell by the bottle, small or large, and have specific ounces in a bottle. 
 
So even though we might have 10 employees, and each want a soda, we have to buy two six packs.
