Specifically, the error message states that an open Warehouse Task (WT) already exists for the specified Handling Unit (HU). This typically occurs when there is an attempt to create a new warehouse task for a handling unit that is already associated with an existing open warehouse task.
  Cause:
  
  Existing Open Warehouse Task: The primary cause of this error is that there is already an open warehouse task associated with the handling unit you are trying to process. This can happen if the handling unit is still in the process of being moved or if it has not been fully processed in the system.
  System Configuration: There may be configuration settings in the SAP system that dictate how handling units and warehouse tasks are managed, which could lead to this error if not set up correctly.

  Check Existing Warehouse Tasks: 
  
  Use transaction codes like /SCWM/WT or /SCWM/HU to check for any existing open warehouse tasks associated with the handling unit in question.
  If you find an open task, you may need to complete or cancel it before proceeding with the new task.
  
  
  
  Complete or Cancel the Open Task: 
  
  If the existing warehouse task is no longer needed, you can cancel it. If it is still required, ensure that it is completed properly before attempting to create a new task for the handling unit.
