• What is the cause and solution for SAP error message COOS018 - Confirmations were created at header level for order & ?

  The SAP error message COOS018 indicates that confirmations were created at the header level for a production order, which means that the system is trying to process confirmations for operations that have already been confirmed at the header level. This can occur in various scenarios, such as when trying to confirm operations individually after a header confirmation has already been made.
  Cause:
  
  Header Confirmation: The most common cause of this error is that the production order has already been confirmed at the header level, which means that all operations under that order have been confirmed collectively.
  Incorrect Confirmation Process: Attempting to confirm individual operations after a header confirmation can lead to this error.
  System Configuration: There may be specific settings in the system that enforce header-level confirmations, preventing individual operation confirmations.
  
  Solution:
  
  Check Confirmations: Verify if the production order has already been confirmed at the header level. You can do this by checking the confirmation history in the production order.
  Avoid Duplicate Confirmations: If the order has been confirmed at the header level, you should not attempt to confirm individual operations. Instead, ensure that all necessary data is included in the header confirmation.
  Use the Correct Confirmation Method: If you need to confirm operations individually, you may need to reverse the header confirmation (if applicable) and then confirm the operations as needed.
  Consult Documentation: Review the SAP documentation or help files related to production order confirmations to understand the correct procedures and implications of header vs. operation confirmations.
  System Configuration Review: If this behavior is not expected, consult with your SAP Basis or configuration team to review the settings related to confirmations in your SAP system.
