• What is the cause and solution for SAP error message /SCMTMS/TOR779 - Carrier cannot be changed by confirmation ?

  The SAP error message /SCMTMS/TOR779 Carrier cannot be changed by confirmation typically occurs in the context of SAP Transportation Management (TM) when there is an attempt to change the carrier for a transportation order (TO) during the confirmation process. This error indicates that the system does not allow the carrier to be modified at this stage due to certain constraints or settings.
  Cause:
  
  Confirmation Process: The carrier is usually locked during the confirmation process to maintain data integrity. Once a confirmation is made, the system expects the carrier to remain unchanged.
  Status of the Transportation Order: The status of the transportation order may not allow changes to the carrier. For example, if the order is already confirmed or in a status that prohibits changes.
  Configuration Settings: There may be specific configuration settings in the SAP TM system that restrict changes to the carrier once certain actions have been taken on the transportation order.
  Business Rules: Organizational policies or business rules may dictate that once a carrier is assigned and the order is confirmed, it cannot be changed.
  
  Solution:
  
  Check the Status: Verify the status of the transportation order. If it is already confirmed, you may need to reverse the confirmation or create a new transportation order with the desired carrier.
  Review Configuration: Consult with your SAP TM configuration team to review the settings related to carrier changes during the confirmation process. Adjustments may be needed based on business requirements.
  Use the Correct Process: If you need to change the carrier, ensure you are following the correct process. This may involve canceling the current confirmation and reassigning the carrier before confirming again.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling transportation orders and carrier assignments.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional insights.
  Transaction Codes: Familiarize yourself with transaction codes related to transportation management, such as /SCMTMS/TOR for transportation orders.
  User Roles and Authorizations: Ensure that the user attempting to make the change has the necessary authorizations to modify transportation orders and carriers.
  Testing in Development: If changes are made to configuration or processes, test them in a development or quality assurance environment before applying them to production.
  
  If the issue persists after following these steps, it may be beneficial to engage with SAP support or your internal SAP team for further investigation.
