SAP Note 22511 - MMIM: Missing lock for customer indep. requirements

Symptom:

If the customer order (e.g. customer independent requirements being processed with transaction MD82) to which a production order is assigned is blocked during backflushing, the reservation is updated anyway. Furthermore, the component is assigned the status "Withdrawal failed". As a result, these components are also listed for error handling.

Cause and prerequisites

Missing block in customer order before the "Post" event.
