• What is the cause and solution for SAP error message WS306 - Document & is a settlement document ?

  The SAP error message WS306: Document & is a settlement document typically occurs in the context of settlement processing in SAP Controlling (CO), especially when dealing with internal orders, projects, or other cost objects.
  
  Cause of the Error WS306
  
  The error indicates that the referenced document is a settlement document.
  Settlement documents are created when costs are settled from one cost object (like an internal order) to another (like a cost center, asset, or profitability segment).
  The system prevents certain postings or actions on documents that are already settlement documents because these documents represent finalized cost allocations.
  This error often occurs when you try to perform an operation (such as reversing, changing, or reposting) on a document that has already been settled or is linked to a settlement process.
  
  
  When Does This Error Occur?
  
  Attempting to reverse or change a settlement document.
  Trying to settle a document that is already a settlement document.
  Posting a document that conflicts with the settlement status of the original document.
  During settlement runs, if the system detects that the document involved is already a settlement document, it may throw this error to prevent inconsistent postings.
  
  
  Solution / How to Resolve WS306
  
  
  Check Document Type:
  
  Verify if the document number mentioned in the error is indeed a settlement document.
  Use transaction codes like FB03 (Display Document) or KOB1 (Order Line Items) to inspect the document.
  
  
  
  Avoid Posting on Settlement Documents:
  
  Do not attempt to reverse or change settlement documents directly.
  Instead, reverse the original document that was settled, if necessary.
  
  
  
  Reverse Original Document:
  
  If you need to correct postings, reverse the original document that was settled, not the settlement document itself.
  After reversal, you can run the settlement again.
  
  
  
  Check Settlement Rules and Periods:
  
  Ensure that settlement rules and periods are correctly maintained.
  Sometimes, incorrect settlement rules or periods can cause conflicts.
  
  
  
  Consult with Controlling Team:
  
  Since settlement documents are part of CO processes, coordinate with the controlling team to understand the impact of reversing or changing documents.
  
  
  
  SAP Notes and Support:
  
  If the issue persists, check SAP Notes for any known bugs or patches related to settlement documents and error WS306.
