Diagnosis
If the error occurred during distribution of

• Material BOMs (BOMMAT message type), document structures (BOMDOC) or
order BOMs (BOMORD), please note that the ALE distribution inbox canonly process one bill of material per IDoc.

• Plant assignments (PALMAT) or material variants (STTMAT) please note
that only assignments to one BOM per IDoc can be distributed. This doesnot restrict the number of assignments per BOM.

System Response
The ALE inbound module cannot process this BOM IDoc. The system canalso no longer accept it if you repost it.
The IDoc remains in the inbox with status 51 (error during posting).

Procedure
Create one IDoc per BOM and per BOM change.
