• What is the cause and solution for SAP error message /SCWM/MFS164 - No open WT exists for HU &1 ?

  The SAP error message /SCWM/MFS164 No open WT exists for HU &1 typically occurs in the context of Warehouse Management (WM) and Handling Unit Management (HUM) within the SAP Extended Warehouse Management (EWM) module. This error indicates that there is no open Warehouse Task (WT) associated with the specified Handling Unit (HU).
  Cause:
  
  No Open Warehouse Task: The primary reason for this error is that the Handling Unit (HU) you are trying to process does not have an associated open Warehouse Task. This can happen if the task has already been completed, canceled, or if it was never created in the first place.
  Incorrect HU Status: The status of the HU may not allow for further processing, or it may not be in a state that is compatible with the operation you are trying to perform.
  System Configuration Issues: There may be configuration issues in the system that prevent the creation of Warehouse Tasks for certain HUs.
  
  Solution:
  
  Check Warehouse Task Status: Verify if there are any open Warehouse Tasks for the specified Handling Unit. You can do this by navigating to the Warehouse Management Monitor or using transaction codes like /SCWM/WT to check the status of Warehouse Tasks.
  Create a New Warehouse Task: If there are no open tasks, you may need to create a new Warehouse Task for the Handling Unit. This can typically be done through the appropriate transaction or process in EWM.
  Review HU Status: Check the status of the Handling Unit to ensure it is in a state that allows for the creation of a Warehouse Task. If necessary, you may need to change the status of the HU.
  Check Configuration: If the issue persists, review the configuration settings in the EWM system to ensure that the processes related to Handling Units and Warehouse Tasks are set up correctly.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed troubleshooting steps related to your specific version of SAP EWM.
