Planning Family Messages

You can manually review and process messages using the MRP/MPS Detail Message Revisions program or automatically process the messages using the MRP/MPS Detail Message Processing program (R3411).

The action messages for DRP, MPS, and MRP are defined in UDC table 34/MT. The character codes are hard-coded. Do not change the character codes in this list.

Each time that you generate a material requirements plan, the system generates action messages to identify situations in which demand requires:

  • Changing the existing supply orders.

  • Placing new orders.

Use the Message Detail - MRP version of the MRP/MPS Detail Message Revisions program to review exception messages from the latest planning generation. These messages might help you evaluate planned and existing orders. You can review the most critical messages first and review other messages in the order that you process them.

Note: For Oracle's JD Edwards EnterpriseOne Demand Flow® Manufacturing (DFM) items only, set the Suppress MRP Messages option in the Item Branch program (P41026) to suppress the display and processing of MRP messages. The Suppress MRP Messages option is used in JD Edwards EnterpriseOne DFM where assemblies and sub-assemblies are inclusive of the line design daily planning, but messages are still needed to drive lower-level demand. If you set the option to suppress MRP message processing, you will not see or be able to process MRP messages for DFM items.
