• What is the cause and solution for SAP error message /SCWM/TW_WT014 - Handling unit &1 already loaded; posting not possible ?

  The SAP error message /SCWM/TW_WT014 Handling unit &1 already loaded; posting not possible typically occurs in the SAP Extended Warehouse Management (EWM) module when there is an attempt to post a handling unit (HU) that has already been loaded onto a transportation unit (TU) or vehicle. This error indicates that the system does not allow the same handling unit to be loaded multiple times, which is a standard practice to maintain data integrity and avoid duplication.
  Cause:
  
  Duplicate Loading Attempt: The handling unit (HU) you are trying to load has already been loaded onto a transportation unit.
  Incorrect Process Flow: The process flow may not have been followed correctly, leading to an attempt to load an already loaded HU.
  System Configuration: There may be specific configurations or settings in the EWM system that enforce strict loading rules.
  
  Solution:
  
  Check the Status of the Handling Unit: Verify the status of the handling unit in the system. You can do this by checking the HU in the EWM interface to see if it is already assigned to a transportation unit.
  Review Load Documents: Look at the load documents or transportation units to confirm that the HU is indeed already loaded. If it is, you will need to determine the next steps based on your warehouse processes.
  Unloading the Handling Unit: If the handling unit needs to be unloaded from the transportation unit, you can perform an unloading operation if your process allows it. This will free up the HU for reloading.
  Correct Process Flow: Ensure that the correct process flow is being followed. If you are trying to load an HU that has already been processed, you may need to adjust your workflow.
  Consult Documentation: Refer to SAP documentation or your internal process documentation for specific instructions on handling HUs and loading processes.
  Contact Support: If the issue persists and you cannot determine the cause, consider reaching out to your SAP support team or consulting with an SAP EWM expert for further assistance.
