Smart SAP Assistant

• What is the cause and solution for SAP error message M_OBOM_WB_GNRL027 - Function is not possible (there are already order BOMs!) ?

  The SAP error message M_OBOM_WB_GNRL027 indicates that a function you are trying to perform is not possible because there are already order Bill of Materials (BOMs) associated with the material in question. This typically occurs when you attempt to create or modify a BOM for a material that already has existing order BOMs.
  Cause:
  The primary cause of this error is that the system has detected existing order BOMs for the material you are working with. In SAP, an order BOM is a specific type of BOM that is linked to production orders, and the system restricts certain operations on materials that already have these BOMs defined.
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check Existing Order BOMs:
  
  Use transaction code CS03 (Display BOM) to check if there are existing order BOMs for the material. This will help you confirm that the BOMs are indeed present.
  
  
  
  Delete or Change Existing Order BOMs:
  
  If you need to create a new BOM, you may need to delete or modify the existing order BOMs. This can be done using transaction code CS02 (Change BOM) or CS05 (Delete BOM).
  Be cautious when deleting BOMs, as this may affect production orders that are already using them.
  
  
  
  Create a New Version:
  
  If you need to maintain the existing BOMs for historical or operational reasons, consider creating a new version of the BOM instead of deleting the existing ones. This can be done in the BOM maintenance transaction.
  
  
  
  Consult with Your Team:
  
  If you are unsure about the implications of deleting or modifying BOMs, consult with your production planning or engineering team to ensure that you are not disrupting any ongoing processes.
  
  
  
  Check Authorization:
  
  Ensure that you have the necessary authorizations to modify or delete BOMs. Lack of proper permissions can also lead to errors.
