• What is the cause and solution for SAP error message /SCWM/TW_UI121 - One handling unit not yet unloaded from HU container ?

  The SAP error message /SCWM/TW_UI121 indicates that there is a handling unit (HU) that has not yet been unloaded from its container. This error typically occurs in the context of warehouse management processes, particularly when dealing with handling units in SAP Extended Warehouse Management (EWM).
  Cause:
  The error is triggered when you attempt to perform an action (such as unloading or moving) on a handling unit that is still contained within another handling unit. This means that the system recognizes that the inner handling unit must first be unloaded from its parent handling unit before any further actions can be taken.
  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Identify the Handling Unit: Determine which handling unit is causing the issue. You can do this by checking the details of the handling unit in the system.
  
  
  Unload the Handling Unit: 
  
  Navigate to the handling unit that is still in the container.
  Perform the unloading process for that handling unit. This typically involves using the appropriate transaction or function in SAP EWM to unload the handling unit from its parent container.
  
  
  
  Verify the Unloading: After unloading, ensure that the handling unit is no longer associated with the parent handling unit. You can check the status of the handling units to confirm that the unloading was successful.
  
  
  Retry the Original Action: Once the handling unit has been successfully unloaded, you can retry the action that initially triggered the error.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP EWM, such as /SCWM/PRDI for handling unit management, or /SCWM/HU for handling unit details.
  Documentation: Refer to SAP Help documentation for Extended Warehouse Management for more detailed procedures on handling units and unloading processes.
  User Roles and Permissions: Ensure that you have the necessary permissions to perform unloading actions in the system.
  System Configuration: If the issue persists, it may be worth checking the configuration settings related to handling units in your SAP EWM system.
  
  If you continue to experience issues after following these steps, it may be beneficial to consult with your SAP support team or refer to SAP Notes for any known issues or patches related to this error message.
