• What is the cause and solution for SAP error message WS809 - Document &1 is not a supplier billing document ?

  SAP Error Message:
  
  WS809 Document &1 is not a supplier billing document
  
  Cause:
  This error occurs when a user tries to perform an operation that requires a supplier billing document (such as referencing or processing a vendor invoice document), but the document number provided (&1) is not recognized by the system as a supplier billing document.
  In SAP, supplier billing documents are typically created in the Logistics Invoice Verification (LIV) component and have specific document types. If the document number entered belongs to a different document type (e.g., a customer invoice, material document, or any other document), the system will raise this error.
  
  Common Scenarios:
  
  Attempting to reference a document in transaction MIRO or related invoice verification transactions, but the document number is incorrect or belongs to a different document type.
  Using a document number from a different module or process (e.g., a customer billing document from SD instead of a vendor invoice).
  Typographical error in the document number.
  The document might have been deleted or not yet posted as a supplier billing document.
  
  
  Solution:
  
  
  Verify Document Number:
  
  Check the document number entered and ensure it is correct.
  Confirm that the document is indeed a supplier billing document (vendor invoice) by checking in transaction MRBR, MIR4, or MB03 (for material documents).
  
  
  
  Check Document Type:
  
  Use transaction MIR4 to display the document and verify its type.
  Ensure the document is a vendor invoice or credit memo.
  
  
  
  Correct Transaction Usage:
  
  Make sure you are using the correct transaction for the intended document type.
  For supplier billing documents, use transactions like MIRO, MIR4, MRBR.
  
  
  
  Check Document Status:
  
  Verify if the document is posted and not deleted or parked.
  If the document is parked, it may not be recognized as a billing document yet.
  
  
  
  Consult Document Flow:
  
  Use transaction MB03 or ME23N to check the document flow and confirm the linkage between purchase order, goods receipt, and invoice document.
  
  
  
  If Document is Missing or Incorrect:
  
  Re-enter the correct supplier billing document number.
  If the document does not exist, create the supplier invoice document properly.
  
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  MIRO – Enter Incoming Invoice
  MIR4 – Display Invoice Document
  MRBR – Release Blocked Invoices
  MB03 – Display Material Document
  ME23N – Display Purchase Order
  
  
  
  Document Types:
  
  Vendor Invoice documents typically have document types like RE (Invoice Receipt).
  Customer billing documents have different document types (e.g., DR).
  
  
  
  SAP Notes:
  
  Check SAP Notes related to invoice verification and document types if the problem persists.
  
  
  
  
  Summary:
  The error WS809 indicates that the document number entered is not recognized as a supplier billing document. Verify the document number, ensure it is a vendor invoice, and use the correct transaction and document type to resolve the issue.
