• What is the cause and solution for SAP error message WG407 - Splitting PO &1 using user exit &2 not possible! ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WG407 - Splitting PO &1 using user exit &2 not possible!
  
  Meaning / Cause:
  
  This error occurs during the splitting of a Purchase Order (PO) in SAP.
  The system tries to split a PO using a user exit (a custom enhancement point in SAP), but the splitting process cannot be completed.
  The placeholders in the message:
  
  &1 = Purchase Order number
  &2 = User exit name or identifier
  
  
  The cause is typically that the user exit logic does not allow the splitting of the PO, or the user exit is not implemented correctly or returns an error.
  It may also occur if the user exit is not properly configured or activated, or if the data conditions in the PO do not meet the criteria expected by the user exit.
  
  
  Common Scenarios:
  
  Custom logic in the user exit prevents splitting due to business rules.
  The user exit raises an exception or error during the splitting process.
  The user exit is missing or incorrectly implemented.
  The PO contains data that violates the assumptions made in the user exit.
  
  
  User Exits Involved:
  
  The user exit involved is usually related to PO splitting logic.
  Common user exits for PO processing include:
  
  EXIT_SAPMM06E_012 (User exit for PO splitting)
  Other enhancement points in the MM Purchasing module.
  
  
  
  
  Solution / How to Fix:
  
  
  Check the User Exit Implementation:
  
  Review the code in the user exit &2 mentioned in the error.
  Verify if the logic allows splitting for the given PO.
  Check for any conditions that cause the exit to reject splitting.
  
  
  
  Debug the User Exit:
  
  Set a breakpoint in the user exit.
  Try to split the PO again and analyze the flow.
  Identify why the exit prevents splitting.
  
  
  
  Adjust Business Logic:
  
  If the exit is too restrictive, modify the logic to allow splitting under the required conditions.
  Ensure that the exit handles all necessary cases gracefully.
  
  
  
  Check Configuration:
  
  Verify that the user exit is properly activated in the system.
  Confirm that the enhancement implementation is assigned correctly.
  
  
  
  Data Consistency:
  
  Check the PO data for inconsistencies or missing information that might cause the exit to fail.
  
  
  
  SAP Notes / Support:
  
  Search for SAP Notes related to WG407 and the specific user exit.
  Apply any relevant patches or corrections.
  
  
  
  
  Additional Information:
  
  PO Splitting is a process where a single PO is divided into multiple POs based on certain criteria (e.g., delivery dates, vendors, plants).
  User exits allow customers to implement their own logic to control or influence the splitting process.
  If the user exit returns an error or does not allow splitting, the system raises WG407.
  This message is informational and points to a customization issue rather than a standard SAP error.
