• What is the cause and solution for SAP error message /SCWM/WHO401 - Warehouse order already contains confirmed WTs. No deletion possible ?

  The SAP error message /SCWM/WHO401 Warehouse order already contains confirmed WTs. No deletion possible typically occurs in the SAP Extended Warehouse Management (EWM) module when you attempt to delete a warehouse order (WO) that has already been confirmed with work tasks (WTs). This means that the system has already processed some of the tasks associated with that warehouse order, and as a result, it does not allow the deletion of the order to maintain data integrity.
  Cause:
  
  Confirmed Work Tasks: The warehouse order you are trying to delete has one or more work tasks that have already been confirmed. Once a work task is confirmed, it is considered completed, and the system prevents any changes to the associated warehouse order.
  System Integrity: SAP EWM is designed to maintain data integrity and prevent inconsistencies in the warehouse management process. Allowing deletion of a warehouse order with confirmed tasks could lead to discrepancies in inventory and task management.
  
  Solution:
  
  Check Confirmed Work Tasks: Review the warehouse order to identify which work tasks are confirmed. You can do this by navigating to the warehouse order in the EWM system and checking the associated work tasks.
  Revoke Confirmation: If it is necessary to delete the warehouse order, you may need to revoke the confirmation of the work tasks. This can typically be done through the transaction for managing work tasks, but be cautious as this may affect inventory and other processes.
  Create a New Warehouse Order: If the deletion is not possible and the warehouse order is no longer needed, consider creating a new warehouse order and processing it as required.
  Consult Documentation: Refer to SAP documentation or your organization's internal guidelines for handling warehouse orders and work tasks, as there may be specific procedures in place.
  Contact Support: If you are unsure about how to proceed or if the situation is complex, consider reaching out to your SAP support team or consulting with an SAP EWM expert.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SCWM/ORDIM (for managing warehouse orders) and /SCWM/WT (for managing work tasks).
  SAP Notes: Check for any SAP Notes related to this error message for additional guidance or patches that may address specific issues.
  Training and Documentation: Ensure that users involved in warehouse management are trained on the processes and implications of confirming and deleting warehouse orders and work tasks.
  
  By following these steps, you should be able to address the error message and manage your warehouse orders effectively.
