Message Types for DRP, MPS, MRP, and RCCP (34/MT)

The system uses 34/MT as the UDC for message types. All the messages are predefined for these message types, which the system displays when you generate DRP, MPS, and so on. Because the character code is hard-coded, you can change the description, but not the function, of the message type.

The system displays messages by type. You can identify which items require attention, based on the action message types. The following table displays what action the system takes when work orders or purchase orders are processed.
