The partner profiles check whether the IDoc type and message type "match" each other. You must therefore make this entry. You also get a specific F4 Help from the mapping: All assigned IDoc types are offered in the corresponding field for each message type and vice versa.
In the example, you should maintain the following mapping:
Message type |
ORDERS (supplied with the standard system) |
Basic type |
ORDERS01 |
Extension |
Z1ORDERS |
Release |
45A |
