• What is the cause and solution for SAP error message /SCWM/SHP_RCV669 - You can't change the carrier, the TU has a fixed vehicle assignment. ?

  The SAP error message /SCWM/SHP_RCV669 indicates that you are trying to change the carrier for a Transportation Unit (TU) that has a fixed vehicle assignment. This typically occurs in the context of SAP Extended Warehouse Management (EWM) when dealing with transportation units and their associated carriers.
  Cause:
  The error arises because the Transportation Unit (TU) is already assigned to a specific vehicle, and the system does not allow changes to the carrier in this state. This is a safeguard to ensure that the logistics process remains consistent and that the assigned vehicle is used for the planned transportation.
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check Vehicle Assignment: Verify the current vehicle assignment for the Transportation Unit. If the TU is already assigned to a vehicle, you may need to unassign it before changing the carrier.
  
  
  Unassign the Vehicle: If you need to change the carrier, you may have to unassign the current vehicle from the Transportation Unit. This can typically be done in the EWM interface where you manage TUs.
  
  
  Change Carrier: Once the vehicle is unassigned, you should be able to change the carrier without encountering the error.
  
  
  Reassign Vehicle: After changing the carrier, if necessary, you can reassign a new vehicle to the Transportation Unit.
  
  
  Check Configuration: If you frequently encounter this issue, it may be worth reviewing the configuration settings related to vehicle assignments and carrier management in your SAP EWM system.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP EWM that deal with Transportation Units, such as /SCWM/TU for managing TUs.
