• What is the cause and solution for SAP error message WGDS_STORAGE_BUS027 - Error during process. Impossible change processing state ?

  The SAP error message:
  WGDS_STORAGE_BUS027: Error during process. Impossible change processing state
  
  Cause
  This error typically occurs in SAP Extended Warehouse Management (EWM) or Warehouse Management (WM) scenarios when there is an attempt to change the processing state of a warehouse task or warehouse order, but the system finds that the change is not allowed due to the current status or business logic constraints.
  Common causes include:
  
  The warehouse task or warehouse order is already in a final or locked status that does not permit further state changes.
  The system is trying to perform an invalid state transition (e.g., from a completed state back to an open or in-process state).
  Inconsistencies or conflicts in the warehouse task or order data, such as missing or incorrect status information.
  Custom enhancements or user exits that incorrectly handle status changes.
  Background jobs or processes trying to update the status while the object is locked or being processed elsewhere.
  
  
  Solution
  To resolve this error, consider the following steps:
  
  
  Check the Current Status:
  
  Verify the current processing state of the warehouse task or warehouse order.
  Use transaction codes like /SCWM/TO_CONF or /SCWM/WO to display the warehouse task or order.
  Confirm if the status allows the intended change.
  
  
  
  Analyze the Process Flow:
  
  Review the business process to ensure that the attempted status change is valid.
  Check if the process is trying to revert a completed task or order, which is usually not allowed.
  
  
  
  Check for Locks or Parallel Processing:
  
  Ensure that no other process or user is currently working on the same warehouse task or order.
  Use transaction SM12 to check for locks.
  
  
  
  Review Custom Code:
  
  If there are user exits, BADIs, or enhancements related to warehouse task or order processing, review them for logic that might prevent status changes.
  
  
  
  Reprocess or Reset Status:
  
  If the warehouse task or order is stuck in an inconsistent state, you may need to reset or reprocess it.
  This might involve canceling and recreating the warehouse task/order or using SAP standard transactions to correct the status.
  
  
  
  Check SAP Notes:
  
  Search for SAP Notes related to WGDS_STORAGE_BUS027 for any known bugs or patches.
  Apply relevant SAP Notes if available.
  
  
  
  Debugging:
  
  If the cause is unclear, debugging the process where the error occurs can help identify the exact reason for the failure.
