2. Enter the invoicing party and amounts, then simulate.
3. Post the document (MIRO).
4. Observe the error: "Maintain the account determination (table T030B) for posting key XXX."

Missing posting key and rule entries for the custom transaction/event key in table T030B in the target systems.

1. In the configuration activity Automatic Account Determination for the area “Sourcing and Procurement,” maintain the account assignment for the relevant transaction/event key. When saving, the activity creates default posting keys and rules if they do not exist.
2. Identify the transport request that contains the posting key/rule entries for the transaction/event key (e.g., XXX) created in the customizing system.
3. Release the transport request and import it into the target system(s) where the error occurs.
4. Verify in the target system that table T030B contains entries for the transaction/event key and required posting rules.
5. Re-test the supplier invoice posting (MIRO). Confirm that delivery cost postings are allowed without errors.
6. Review the G/L account assignments in Automatic Account Determination after the import. If they are not as expected, adjust the accounts in the customizing system, create a new transport, and import again.
7. Perform the full test in a test system before moving changes to production.
