Why are account assignments missing from required entry fields for some documents from phase 1 even though validation of document splitting is active with an error message?
You reset cleared items in phase 1. Clearing documents do not receive the document splitting characteristics during posting because they receive the document splitting information from the cleared items during the migration. This relationship is lost due to the clearing reset. The BAdI can enrich the documents, or you can customize a clearing relationship for these documents in particular. To avoid this situation, we recommend that you do not use transaction FBRA (Reset Cleared Items) during phase 1. In addition, if the document to be reversed does not contain this account assignment, reversal documents will be posted without account assignments even though document splitting validation is active.
