• What is the cause and solution for SAP error message /SCWM/MFS162 - WT &1 already sent to PLC ?

  The SAP error message /SCWM/MFS162 WT &1 already sent to PLC typically occurs in the context of the SAP Extended Warehouse Management (EWM) system, particularly when dealing with the Material Flow System (MFS) integration. This error indicates that a Warehouse Task (WT) has already been sent to the Programmable Logic Controller (PLC) and cannot be processed again.
  Cause:
  
  
  Duplicate Processing: The error usually arises when there is an attempt to resend a Warehouse Task that has already been communicated to the PLC. This can happen due to:
  
  A manual retry of a task that has already been processed.

  Configuration Issues: There may be configuration settings in the MFS that are not aligned with the expected behavior of the warehouse processes.
  
  
  Solution:
  
  
  Check Task Status: Verify the status of the Warehouse Task in the EWM system. If the task has already been processed, you may need to acknowledge or complete it in the system rather than trying to resend it.
  
  
  Review PLC Communication: Ensure that the communication between SAP EWM and the PLC is functioning correctly. Check for any logs or error messages in the PLC that might indicate issues with task processing.
  
  
  Adjust Task Handling: If the task needs to be reprocessed, you may need to cancel the existing task and create a new one, depending on your business process requirements.
  
  
  Configuration Review: Review the MFS configuration settings in SAP EWM to ensure they are set up correctly. This includes checking the integration settings and ensuring that the system is configured to handle task statuses appropriately.
