Hi Venkat
The VBRK-KNUMA field is normally only filled in the actual rebate documents. So billing documents
created from partial payments etc made in VBo2 etc. When you post an F2 biling document that is relevant for an agreement the field would not be filled normally.
So you have partial payments or manual accrauls that were posted where the KNUMA field is not filled ?
VBOF updates missing relevant rebate conditions and posts an FI document where changes are made. It cannot update an existing VBRK entry.
If you have missing values on existing documents you will have to cncel and recreated the documents correctly or create a small ABAP report to update the VBRK table on the affected documents.
