Understanding Setting Up UDCs for Parts Planning

Before you can generate and review a parts plan, you must set up information that the system uses to process the plan. For example, you must set up a table of user-defined quantity types that the system uses to calculate and display the supply and demand of parts. You must also specify the action messages that you want to appear when the system detects a conflict between the availability and the demand for a part.

In addition, you can set up different versions of the supply and demand inclusion rules to accommodate different types of parts plans that you want to generate. For example, you can generate a long-range parts plan and a short-range parts plan. You use supply and demand inclusion rules to specify the document types that you want the system to include when it processes each plan.

Before you can use the parts planning features, you must set up these UDCs:

• Quantity Type (34/QT)

• MRP calculation display (34/MM)

• MRP action messages (34/MT)

The system uses these codes to calculate and display the availability of parts. The system also uses these codes to determine which action messages to display when it detects a conflict between the availability and the demand for a part.
