  The SAP error message /SCWM/SERIAL121 indicates that a Unique Item Identifier (UII) has already been assigned to a specific delivery item. This error typically occurs in the context of warehouse management and logistics, particularly when dealing with serial numbers or unique identifiers for items in a delivery.
  Cause:
  The error is triggered when:

  Correct the Assignment:
  
  If the UII is indeed assigned to another delivery, you will need to either:
  
  Unassign it from the existing delivery if it is no longer needed there.
  Use a different UII for the new delivery item you are trying to assign.
