  The SAP error message /ACCGO/OE_MSG166 with the description "109 posting is already done for delivery &1" typically occurs in the context of logistics and accounting when there is an attempt to post a document (like an invoice or a goods movement) for a delivery that has already been processed.
  Cause:
  
  Duplicate Posting: The most common cause of this error is that there has already been a posting made for the specified delivery. This could happen if the user attempts to post the same delivery multiple times.
  Incorrect Document Flow: There may be an issue with the document flow where the system believes that the delivery has already been fully processed.
  System Configuration: In some cases, the configuration settings in the system may not allow for certain types of postings after a delivery has been completed.
  
  Solution:
  
  Check Document Status: Verify the status of the delivery in question. You can do this by checking the delivery document in the SAP system to see if it has already been posted.
  Review Posting History: Look at the posting history for the delivery to confirm if a posting has already been made. This can be done through transaction codes like VL03N (Display Outbound Delivery) or MB03 (Display Material Document).
  Avoid Duplicate Actions: Ensure that users are not attempting to post the same delivery multiple times. Implement checks or training to prevent this from happening.
  Consult with Technical Team: If you believe that the posting should be allowed (for example, if there was an error in the previous posting), consult with your technical team or SAP support to investigate further. They may need to check for any inconsistencies in the database or application logic.
  Use Transaction Codes: Use relevant transaction codes to analyze the situation:
  
  VL02N (Change Outbound Delivery) to check the delivery details.
  MB51 (Material Document List) to see the postings related to the delivery.
