  Error Message Overview
  
  Message ID: VN066
  Message Text: "Cannot be processed: Message & has been changed"
  Module: Vendor Invoice Verification (MM - Materials Management)
  
  
  Cause
  The error VN066 typically occurs during the processing of vendor invoices or credit memos in the SAP system. It indicates that a particular message (usually a communication or document message related to the invoice) has been changed or updated in the system after the invoice was initially created or referenced.
  More specifically:
  
  The system detects that the message (e.g., a text or note attached to the invoice or purchase order) has been modified since the last processing step.
  This change causes a conflict or inconsistency, preventing further processing of the invoice.
  It often happens when the invoice references a message that has been altered or deleted in the background, or when the message status has changed unexpectedly.
  
  
  Common Scenarios Leading to VN066
  
  A message attached to the invoice or purchase order was edited or deleted after the invoice was created.
  The invoice is being processed in a background job or workflow, and the message was changed in the meantime.
  Invoices referencing purchase orders where the PO messages have been updated.
  Custom developments or user exits that modify messages during invoice processing.
  
  
  Solution / How to Resolve
  
  
  Check the Message Status:
  
  Go to the invoice or purchase order and review the messages attached.
  Verify if any message has been changed, deleted, or updated recently.
  
  
  
  Recreate or Update the Message:
  
  If the message was deleted or changed, recreate or restore the original message.
  Ensure that the message content matches what the invoice expects.
  
  
  
  Reprocess the Invoice:
  
  After correcting the message, try to reprocess the invoice.
  If the invoice is stuck in a certain status, reset or delete the invoice document and recreate it if necessary.
  
  
  
  Check for Custom Code:
  
  Review any user exits, BADIs, or enhancements that might be modifying messages during invoice processing.
  Ensure that these modifications are consistent and do not cause message inconsistencies.
  
  
  
  SAP Notes and Support:
  
  Check SAP Notes for any known bugs or patches related to message handling in invoice verification.
  For example, SAP Note 123456 (example) might address similar issues (replace with actual note if available).
