54 Certification Study Guide Series: IBM Maximo Asset Management V7.1 The four attributes that should be defined when creating a conversion factor are From Unit of Measure, To Unit of Measure, Conversion Factor, and Item Number. All of them are required, except for the Item Number. This last attribute should be used when the conversion is directly associated to the item. For example, a CASE for one item might be 24 and for another item it might be 36. However, the numbers 24 and 36 represent the quantity within the case and not the issue unit. If you receive a case of 24 gaskets, but you issue them in sets of four, then the conversion ratio for CASE in this example would be 6. You can assign the conversion of a CASE of 24 gaskets to be 6, and associate it to the item gaskets. Figure 4- 3 shows the window for creating and modifying conversion factors.

Purchasing managers may create budgets, create and manage purchase orders, and manage vendor relationships based on commodities.
