  The SAP error message BOM251 indicates that there is a consistency check failure when creating a Bill of Materials (BOM) header. This error typically arises due to issues with the data being entered or the configuration of the BOM. Here are some common causes, solutions, and related information for this error:
  Causes:
  
  Missing Required Fields: Certain mandatory fields in the BOM header may not be filled out correctly or are left blank.
