• What is the cause and solution for SAP error message VL474 - Picking/putaway has already started in decentralized WMS ?

  The SAP error message VL474 ("Picking/putaway has already started in decentralized WMS") typically occurs in scenarios where there is an attempt to perform a picking or putaway operation in a decentralized Warehouse Management System (WMS) while the process has already been initiated or is in progress. This error is common in environments where SAP Extended Warehouse Management (EWM) or other decentralized WMS solutions are integrated with SAP ERP.
  Cause:
  
  Concurrent Operations: The error usually arises when a picking or putaway process is already active for the same warehouse task or handling unit. This can happen if multiple users or processes are trying to initiate the same operation simultaneously.
  System Configuration: There may be configuration issues in the integration between the decentralized WMS and the SAP ERP system, leading to inconsistencies in the status of warehouse tasks.
  Incomplete Transactions: If a previous picking or putaway transaction was not completed or was interrupted, the system may still consider that operation as active.
  
  Solution:
  
  Check Active Tasks: Verify if there are any active picking or putaway tasks for the same material or handling unit. You can do this by checking the relevant transaction codes in the WMS or ERP system.
  Complete or Cancel Existing Tasks: If there are active tasks, either complete them or cancel them if they are no longer needed. This will free up the system to allow new operations.
  Review User Actions: Ensure that users are not trying to perform the same operation simultaneously. Implementing proper user training and guidelines can help mitigate this issue.
  System Logs: Check system logs for any errors or warnings that might provide additional context about the issue. This can help identify if there are underlying problems with the system configuration.
  Integration Check: Review the integration settings between the decentralized WMS and SAP ERP to ensure that they are correctly configured. This includes checking for any middleware or interfaces that may be involved.
  Consult Documentation: Refer to SAP documentation or support notes related to VL474 for any specific recommendations or patches that may address the issue.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as VL01N (Create Outbound Delivery), VL02N (Change Outbound Delivery), and LT03 (Convert TO) to manage warehouse tasks.
  SAP Notes: Search for SAP Notes related to VL474 for any known issues or fixes that may apply to your version of SAP.
  User Roles and Authorizations: Ensure that users have the appropriate roles and authorizations to perform picking and putaway operations without conflicts.
  
  By following these steps, you should be able to resolve the VL474 error and ensure smooth operations in your decentralized WMS environment.
