• What is the cause and solution for SAP error message CK081 - Material & plant &: alternative BOM & not found ?

  The SAP error message CK081 indicates that the system could not find an alternative Bill of Materials (BOM) for a specific material and plant combination. This error typically arises during the process of material costing or when trying to create a production order, and it suggests that the system is looking for an alternative BOM that has not been defined in the system.
  Causes:
  
  Missing Alternative BOM: The most common cause is that the alternative BOM for the specified material and plant has not been created or is not available in the system.
  Incorrect Configuration: The configuration settings for BOMs may not be set up correctly, leading to the system not recognizing the alternative BOM.
  Plant-Specific Issues: The alternative BOM may exist for a different plant but not for the one specified in the error message.
  Versioning Issues: The BOM version may not be active or may have been deleted or archived.
  Authorization Issues: The user may not have the necessary authorizations to view or access the alternative BOM.
  
  Solutions:
  
  
  Create or Update Alternative BOM:
  
  Check if the alternative BOM exists for the specified material and plant. If it does not, create it using transaction code CS01 (Create BOM).
  If it exists but is not active, you may need to activate it or create a new version.
  
  
  
  Check BOM Configuration:
  
  Review the BOM configuration settings in the system to ensure that alternative BOMs are set up correctly. This can be done using transaction code CS02 (Change BOM) to verify the details.
  
  
  
  Verify Plant-Specific BOMs:
  
  Ensure that the alternative BOM is created for the correct plant. You can check this using transaction code CS03 (Display BOM) to see if the BOM is plant-specific.
  
  
  
  Check BOM Status:
  
  Ensure that the BOM is not marked for deletion or archived. You can check the status of the BOM in the BOM details.
  
  
  
  Authorization Check:
  
  Verify that the user has the necessary authorizations to access the BOM. This may require coordination with the SAP security team.
