  SAP Error Message:
  VO704 Unexpected return code CHECK_CHANGES: &
  
  1. Cause
  This error typically occurs during the processing of sales documents (e.g., sales orders, quotations) in the Sales and Distribution (SD) module. The message indicates that the function module or BAdI responsible for checking changes in the sales document has returned an unexpected return code.
  
  The message VO704 is related to the CHECK_CHANGES routine, which is part of the sales document processing logic.
  The placeholder & in the message usually contains the actual return code or error text returned by the check routine.
  The error arises when a custom or standard validation/check in the sales document change process returns a code that the system does not expect or cannot handle properly.
  This can happen due to:
  
  Custom enhancements (user exits, BADIs) that implement additional checks and return unexpected values.
  Inconsistencies or errors in the sales document data.
  Issues in the standard SAP code or patches that affect the CHECK_CHANGES logic.
  
  
  
  
  2. Solution
  To resolve this error, follow these steps:
  a) Identify the exact return code/message
  
  Check the full error message in the system to see what the placeholder & contains.
  Look into the sales document change process to find which check or validation is causing the unexpected return code.
  
  b) Analyze custom enhancements
  
  Review any custom user exits or BADIs related to sales document change checks, such as:
  
  USEREXIT_SAVE_DOCUMENT_PREPARE
  USEREXIT_SAVE_DOCUMENT
  BAdI SD_SALES_DOCUMENT_CHECK
  
  
  Check if these enhancements return any custom return codes or messages that are not handled by the standard SAP logic.
  
  c) Debug the sales document change process
  
  Use transaction VA02 (Change Sales Order) and reproduce the error.
  Set breakpoints in the function modules or methods related to CHECK_CHANGES (e.g., SD_SALES_DOCUMENT_CHECK BAdI implementations).
  Trace the return codes and see where the unexpected code is generated.
  
  d) Correct the return codes
  
  Ensure that any custom code returns only expected and valid return codes.
  If the error is due to inconsistent data, correct the data in the sales document.
  
  e) Apply SAP Notes
  
  Search for SAP Notes related to message VO704 or CHECK_CHANGES errors.
  Apply any relevant patches or corrections provided by SAP.
