This process describes how the message determination is carried out in the case of a summarized JIT call. Message determination always appears when you create a new JIT call.
You have determined the necessary prerequisites for the summarized JIT call (control cycle with appropriate replenishment strategy, scheduling agreement etc.) Please readCreating and Transmitting a Summarized JIT Call.
In the SAP standard system, Customizing is already set for the message determination. However, you can carry out extensions in the customer name period. For the message determination the following are necessary:
Condition records are not provided in the SAP standard system; you have to fill out the condition tables yourself.
Detailed information on message determination can be found in the section Message Determination ff.
The Customizing settings for message determination schema, partner function and message type determine which messages have been permitted and which partner functions can be used with these message types.
When searching for suitable condition records, the message determination covers the tables in the message determination schema, partner functions and message types.
Using the partner function in the JIT call profile, the system can find the message partner, to whom the message is to be transmitted, with the vendor master record. The vendor, who is maintained in the corresponding scheduling agreement with this partner function, is transferred into the JIT call as message partner.
