• What is the cause and solution for SAP error message /SCWM/SHP_RCV142 - An assignment already exists between TU &1 and delivery &2 ?

  The SAP error message /SCWM/SHP_RCV142 indicates that there is already an existing assignment between a Transportation Unit (TU) and a delivery. This typically occurs in the context of SAP Extended Warehouse Management (EWM) when trying to assign a delivery to a Transportation Unit that is already linked to another delivery.
  Cause:
  
  Duplicate Assignment: The most common cause is that the Transportation Unit (TU) you are trying to assign to a delivery is already assigned to another delivery.
  System Configuration: There may be system settings or configurations that prevent the reassignment of TUs once they are linked to a delivery.
  User Error: The user may be attempting to assign the same TU to multiple deliveries without realizing it.
  
  Solution:
  
  
  Check Existing Assignments: 
  
  Use transaction codes like /SCWM/TO or /SCWM/TU to check the current assignments of the Transportation Unit. Look for any existing deliveries linked to the TU.
  
  
  
  Unassign the TU: 
  
  If the TU is incorrectly assigned, you may need to unassign it from the existing delivery before reassigning it to the new delivery. This can typically be done through the TU management screen.
  
  
  
  Review Delivery Status: 
  
  Ensure that the delivery you are trying to assign the TU to is in a status that allows for assignment. Some statuses may restrict changes.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help files related to Transportation Units and deliveries for any specific guidelines or restrictions that may apply.
