BOMs with the |@03@ indicator cannot be distributed via ALE.
A possible cause for this are the settings maintained in thedistribution model in ALECustomizing for filtering or class assignment. For BOMs that have beenchanged using engineering change management, a distribution lock on BOMlevel can be the cause.

System Response
