  Error Message
  WS843: Reversal docs cannot be reopened (document & is reversal doc for &)
  
  Cause
  This error occurs when you try to reopen a document that is a reversal document in SAP. In SAP, reversal documents are created to reverse or cancel the effects of an original document (e.g., reversing a posted invoice or payment). Once a reversal document is posted, the system does not allow reopening of that reversal document because:
  
  Reversal documents are considered final and are linked to the original document.
  Reopening a reversal document could cause inconsistencies in financial data.
  The system enforces data integrity by preventing changes to reversal documents.
  
  
  When does this happen?
  
  You try to reopen a document (e.g., for editing or changing) in transaction codes like FB08, FBRA, or other document processing transactions.
  The document you are trying to reopen is itself a reversal document (not the original document).
  The system detects that the document is a reversal and blocks the reopening.
  
  
  Solution / How to resolve
  
  
  Identify the document type:
  
  Check if the document you are trying to reopen is a reversal document.
  You can do this by looking at the document flow or document header in transactions like FB03 or FB02.
  
  
  
  Do not attempt to reopen reversal documents:
  
  SAP does not allow reopening reversal documents.
  Instead, if you need to correct something, you should work with the original document or create a new reversal or adjustment document.
  
  
  
  If you need to change the original document:
  
  Reopen or adjust the original document if allowed.
  If the original document is also blocked, you may need to reverse the reversal document first (if business process allows), or create a new correcting document.
  
  
  
  Business process check:
  
  Confirm with your finance or controlling team about the correct process to handle corrections.
  Usually, corrections are done by posting new documents rather than reopening reversal documents.
  
  
  
  
  Additional Information
  
  Reversal documents are created using transactions like FB08 (Document Reversal), MR8M (Invoice Cancellation), or similar.
  The system links reversal documents to the original document via reference fields.
  Attempting to reopen reversal documents violates SAP's document integrity rules.
  If you need to "undo" a reversal, you typically post a new document to reverse the reversal (i.e., re-post the original document or create a new document).
  Always ensure proper authorization and follow company policies when handling financial document reversals.
