• What is the cause and solution for SAP error message /SCWM/UI_PACKING051 - There are open HU WTs; Repacking only possible via WT ?

  The SAP error message /SCWM/UI_PACKING051 indicates that there are open Handling Unit (HU) Warehouse Tasks (WTs) that prevent the repacking of handling units. This error typically occurs in the SAP Extended Warehouse Management (EWM) module when you attempt to repack a handling unit that is currently involved in an open warehouse task.
  Cause:
  
  Open Warehouse Tasks: The primary cause of this error is that there are existing open warehouse tasks associated with the handling unit you are trying to repack. These tasks could be for picking, putaway, or other warehouse operations that have not yet been completed.
  System Configuration: The system may be configured to restrict repacking operations when there are open tasks to ensure data integrity and proper inventory management.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Open Warehouse Tasks:
  
  Use transaction codes like /SCWM/WT or /SCWM/HU to check for any open warehouse tasks associated with the handling unit in question.
  Identify the tasks that are open and determine their status.
  
  
  
  Complete or Cancel Open Tasks:
  
  If the open tasks are no longer needed, you can cancel them.
  If they are still required, complete the tasks as necessary. This may involve performing the picking, putaway, or other operations that the tasks represent.
  
  
  
  Repack After Tasks are Closed:
  
  Once all open warehouse tasks related to the handling unit are completed or canceled, you should be able to proceed with the repacking operation without encountering the error.
  
  
  
  Use Warehouse Task for Repacking:
  
  If the system requires it, you may need to create a new warehouse task specifically for the repacking operation. This can be done through the appropriate EWM transactions.
  
  
  
  Related Information:

  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP EWM, such as /SCWM/WT, /SCWM/HU, and /SCWM/PR (for processing repacking).
  
  By following these steps and understanding the underlying concepts, you should be able to resolve the error and successfully perform the repacking operation in SAP EWM.
