PK29A

In financial accounting, down payments that have been made with posting key 29, special G/L indicator A must be in payment block A automatically. This is not the case.

Some payments (displayed in FBL1N) are not in the payment block when F110 is run.

The vendors have not been blocked for payment. We have not found any default settings in the posting key 29, as well as there are no manual changes in the documents that are affected.

Would you please advise what is causing this inconsistency? Why are some documents (PK29A) not in payment block automatically, while others are?
