When parts or assemblies are stored in the storeroom, or used in Bills of Materials, the unit of measure must be defined. It is important to know if a particular wire is stored in inventory, if it is 100 inches, 100 feet, 100 yards, etc. This definition is required so that when items are counted and removed from stock inventory, it is clear what the quantity numbers represent. Other examples might be ounces, pounds, quarts, gallons, pints, milliliters, liters, etc.

It is also possible to purchase material in different units of measure than the material is accounted for in stock inventory and bills of materials. For example, wire might be purchased in feet, yards or miles, but because of the way that it is used in manufacturing, is probably stored and issued in inches. All units of measure, for both stock inventory and purchasing, are to be entered in this screen, if not already available. Once a unit of measure is entered in this screen, it can never be removed as the value of any purchases and inventory depends on having a unit of measure associated with it.

Manex is provided with a number of units of measures. The length of the unit of measure field is 4 characters.

« Purchasing units of measure, if different than the stocking units of measure, must have a conversion factor entered in order for MANEX Material Requirements Planning and Purchasing modules to correctly interpret the amount of material required. Identifying the purchasing unit and the stocking unit and a factor between the two does this. For example, 1 foot = 12 inches, and 12 is the conversion factor.
