Smart SAP Assistant

• What is the cause and solution for SAP error message M_OBOM_WB_GNRL028 - Function is not possible (there are already manually adapted order BOMs) ?

  The SAP error message M_OBOM_WB_GNRL028 indicates that a function cannot be executed because there are already manually adapted order Bill of Materials (BOMs) associated with the order. This typically occurs when you are trying to perform an operation that requires a standard BOM, but the system detects that there are custom changes made to the BOM for that specific order.
  Cause:
  
  Manual Adjustments: The order BOM has been manually adjusted or customized for specific production orders, which prevents the system from applying standard BOM changes or operations.
  Order-Specific BOM: The system is designed to protect the integrity of manually adjusted BOMs, as they may contain critical changes that are not compatible with the standard BOM.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Review the BOM: Check the BOM associated with the order to identify any manual adjustments. You can do this by navigating to the BOM management transaction (e.g., CS03) and reviewing the details.
  
  
  Revert Changes: If the manual changes are not needed, you can revert the BOM to the standard version. This may involve deleting the order-specific BOM or resetting it to the original state.
  
  
  Create a New Order: If the manual changes are necessary and cannot be reverted, consider creating a new production order that does not have the manual BOM adjustments.
  
  
  Consult Documentation: Review SAP documentation or consult with your SAP support team for specific instructions on handling order BOMs and the implications of manual adjustments.
  
  
  Use Alternative Functions: If applicable, look for alternative functions or transactions that allow you to work with the BOM without conflicting with the manual adjustments.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), and CS03 (Display BOM) for managing BOMs.
  SAP Notes: Check SAP Notes for any known issues or patches related to BOM management that might address this error.
  User Roles and Permissions: Ensure that you have the necessary permissions to make changes to BOMs and production orders.
  Training and Documentation: Consider training sessions or documentation on BOM management in SAP to better understand how to handle such situations in the future.
  
  By following these steps, you should be able to address the error and continue with your operations in SAP.
