Diagnosis
You want to replace a material in BOMs with a new material. The systemchecks whether a change is allowed. Under certain conditions, thechange is not carried out, for example if:

• an object is locked


• the authorization group of an object is not within the value range in
your current user profile

• no management record for the change number exists for the BOM to be
changed
This message refers you to the log, which tells you the reason why themass change was cancelled.
