MF312 - Details

• The SAP error message MF312 ("Delete function not possible. Lower-level elements exist.") typically occurs when you attempt to delete a higher-level item in a bill of materials (BOM) or a similar hierarchical structure, but there are still dependent lower-level elements (sub-items or components) associated with it. This is a protective measure to prevent the accidental deletion of important data that is still in use.
  
  Cause:
  
  Dependent Elements: The higher-level item you are trying to delete has one or more lower-level elements (sub-items) that are still active or in use.
  BOM Structure: In a BOM, if you try to delete a parent item, the system checks for any child items. If any child items exist, the deletion is not allowed.
  Data Integrity: SAP enforces data integrity by preventing the deletion of items that are still referenced in other documents or processes.
