Smart SAP Assistant

• What is the cause and solution for SAP error message /SCWM/SHP_RCV674 - You can't change the carrier, the vehicle has fixed TU assignments. ?

  The SAP error message /SCWM/SHP_RCV674 indicates that you are trying to change the carrier for a shipment or transportation unit (TU) that has fixed assignments. This typically occurs in the context of SAP Extended Warehouse Management (EWM) when there are constraints on modifying certain attributes of a transportation unit that has already been assigned to specific tasks or processes.
  Cause:
  
  Fixed TU Assignments: The vehicle or transportation unit (TU) has already been assigned to specific tasks, and these assignments are fixed. This means that the system does not allow changes to the carrier because it could disrupt the existing assignments.
  Status of the TU: The transportation unit may be in a status that does not permit changes, such as being in transit or already loaded.
  Configuration Settings: There may be configuration settings in the system that prevent changes to certain attributes of the transportation unit once it has been assigned.
  
  Solution:
  
  Check TU Status: Verify the status of the transportation unit. If it is in a status that allows changes, you may need to change the status first before attempting to change the carrier.
  Release Assignments: If possible, release or unassign the existing tasks or assignments associated with the transportation unit. This may involve canceling or modifying the existing assignments.
  Create a New TU: If changing the carrier is essential and the current TU cannot be modified, consider creating a new transportation unit with the desired carrier and reassigning the relevant tasks to this new TU.
  Consult Configuration: Review the configuration settings in SAP EWM related to transportation units and carrier assignments. There may be specific settings that need to be adjusted to allow for changes.
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting the SAP Help Portal for further assistance.
  
  Related Information:
  
  SAP EWM Documentation: Review the official SAP documentation for Extended Warehouse Management to understand the implications of TU assignments and carrier changes.
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP EWM that can help you manage transportation units and their assignments (e.g., /SCWM/TU, /SCWM/SHIP, etc.).
  User Exits and BAdIs: If your organization has custom developments, check if there are any user exits or BAdIs that might affect the behavior of TU assignments and carrier changes.
  
  By following these steps, you should be able to address the error message and make the necessary changes to your transportation unit assignments.
