• What is the cause and solution for SAP error message 29603 - BOMs exist for usage & (change & from & to &) ?

  The SAP error message 29603 indicates that there are existing Bill of Materials (BOMs) for a specific usage that you are trying to change. This error typically occurs when you attempt to modify or delete a BOM that is still in use or has dependencies that prevent the change.
  Cause:
  
  Existing BOMs: The primary cause of this error is that there are BOMs defined for the specified usage, and the system does not allow changes to be made while these BOMs exist.
  Usage Type: The usage type you are trying to change may be linked to production, planning, or other processes that require the BOM to remain intact.
  Dependencies: There may be other objects or processes that depend on the BOM, such as production orders, sales orders, or material requirements planning (MRP).
  
  Solution:
  
  Check Existing BOMs: Use transaction codes like CS03 (Display BOM) to check the existing BOMs for the specified usage. Identify if there are any BOMs that need to be modified or deleted.
  Delete or Change BOMs: If you need to change the BOM, you may need to delete the existing BOMs first (if they are no longer needed) or modify them as required.
  Change Usage: If the BOMs are still required, consider changing the usage type instead of deleting or modifying the existing BOMs.
  Consult Documentation: Review the documentation for the specific BOM usage to understand the implications of changing or deleting BOMs.
  Check Dependencies: Ensure that there are no active production orders or other dependencies that would prevent the change. You may need to complete or cancel these orders before proceeding.
