Smart SAP Assistant

• What is the cause and solution for SAP error message /SCWM/TW_WT008 - HU &1 has an already an open warehouse task (WT &2) ?

  The SAP error message /SCWM/TW_WT008 indicates that a Handling Unit (HU) is already associated with an open Warehouse Task (WT). This typically occurs in the Extended Warehouse Management (EWM) module when you attempt to perform an action on a Handling Unit that is already linked to an existing Warehouse Task that has not yet been completed.
  Cause:
  
  Open Warehouse Task: The Handling Unit (HU) you are trying to process is already linked to an open Warehouse Task (WT). This means that there is an ongoing operation that involves this HU, and the system does not allow you to initiate another operation until the current one is completed.
  System Configuration: There may be specific configurations or settings in your EWM system that enforce strict handling of HUs and WTs, preventing concurrent operations.
  
  Solution:
  
  
  Check Open Warehouse Tasks: 
  
  Use transaction codes like /SCWM/WT or /SCWM/HU to check the status of the Warehouse Tasks and Handling Units. Identify the open Warehouse Task associated with the HU.
  You can also use the EWM Monitor to view the status of Warehouse Tasks and Handling Units.
  
  
  
  Complete or Cancel the Open Warehouse Task:
  
  If the open Warehouse Task is no longer needed, you can cancel it. If it is still required, ensure that it is completed before attempting to process the HU again.
  If the task is stuck or needs to be reprocessed, you may need to follow your organization's procedures for handling such cases.
  
  
  
  Review Task Management:
  
  Ensure that your warehouse processes are being followed correctly. If tasks are being left open unintentionally, review the processes to identify any gaps or issues.
  
  
  
  Consult Documentation: 
  
  Refer to SAP documentation or your organization's internal documentation for specific procedures related to handling Warehouse Tasks and Handling Units.
  
  
  
  Contact Support: 
  
  If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with SAP support for further assistance.

  EWM Configuration: Understanding the configuration settings in EWM can help prevent similar issues in the future. This includes settings related to task creation, handling unit management, and warehouse process flows.
