• What is the cause and solution for SAP error message CK279 - BOM already exploded for costing run & & ?

  The SAP error message CK279, which states "BOM already exploded for costing run & &," typically occurs during the costing process when the system detects that a Bill of Materials (BOM) has already been exploded for a specific costing run. This can happen in various scenarios, such as when you attempt to re-explode a BOM that has already been processed for costing.
  Cause:
  
  Duplicate Costing Run: The error usually arises when there is an attempt to explode a BOM that has already been processed in the current costing run.
  Costing Variant Settings: The settings in the costing variant may not allow for re-explosion of the BOM.
  Incomplete or Incorrect Data: There may be issues with the data in the BOM or the material master that prevent the system from processing the costing correctly.
  
  Solution:
  
  Check Costing Run Status: Verify if the BOM has already been exploded for the costing run you are trying to execute. You can check the status of the costing run in the relevant transaction (e.g., CK40N).
  Use a Different Costing Run: If you need to re-explode the BOM, consider using a different costing run number that has not been processed yet.
  Reset the Costing Run: If you need to reprocess the same costing run, you may need to reset or delete the existing costing run. This can be done using transaction CKR1 (Reset Costing Run) or CKR2 (Delete Costing Run).
  Review BOM and Material Master: Ensure that the BOM and material master data are complete and correct. Check for any inconsistencies or missing information that might be causing the issue.
  Consult Documentation: Review SAP documentation or notes related to the error message for any specific guidance or updates that may apply to your version of SAP.
