• What is the cause and solution for SAP error message /SCWM/UI_PACKING160 - Open WTs exist! Check Return transfer being created ?

  The SAP error message /SCWM/UI_PACKING160 indicates that there are open Warehouse Tasks (WTs) that need to be addressed before a return transfer can be created. This error typically occurs in the context of SAP Extended Warehouse Management (EWM) when trying to process a return transfer for goods that are still associated with open WTs.
  Cause:
  
  Open Warehouse Tasks: The primary cause of this error is that there are existing open WTs that have not been completed. These tasks may involve picking, packing, or other warehouse operations that need to be finalized before a return transfer can be processed.
  Incomplete Processes: The WTs may be related to the same stock or items that you are trying to return, and the system prevents the creation of a return transfer to avoid inconsistencies in inventory management.
  System Configuration: There may be specific configurations or settings in the EWM system that enforce this check to ensure that all tasks are completed before allowing further processing.
  
  Solution:
  
  
  Check Open Warehouse Tasks:

  Complete or Cancel Open WTs:
  
  If the WTs are still relevant, complete them by performing the necessary actions (e.g., picking, packing).

  Review Task Status:
