• What is the cause and solution for SAP error message WS898 - Partner reversal with posting partner &1 not allowed (document &2) ?

  The SAP error message:
  WS898 Partner reversal with posting partner &1 not allowed (document &2)
  
  Meaning / Cause:
  This error occurs during a reversal (cancellation) of a document in SAP when the system detects that the reversal is being attempted with a posting partner that is not allowed or not maintained for the original document. In other words, the reversal transaction tries to use a partner function or partner number that is inconsistent or not permitted based on the original document's partner data.
  Typically, this happens in scenarios involving:
  
  Partner determination in FI documents (e.g., customer/vendor partner functions).
  Reversals where the partner data must match or comply with certain rules.
  Posting partner is mandatory or restricted in the system configuration, and the reversal does not meet these requirements.
  
  
  When does it occur?
  
  During document reversal (e.g., transaction FB08, FBRA).
  When the reversal document tries to post with a partner that differs from the original or is not allowed.
  In systems where partner functions are strictly controlled for postings and reversals.
  
  
  Solution / How to fix:
  
  
  Check the Posting Partner Configuration:
  
  Verify the partner functions and posting partner settings in the relevant customizing.
  Transaction: SPRO ? Financial Accounting ? Accounts Receivable and Accounts Payable ? Business Transactions ? Incoming Invoices/Credit Memos ? Partner Determination.
  Ensure that the posting partner used in the reversal is allowed and correctly maintained.
  
  
  
  Check the Original Document Partner Data:
  
  Display the original document (using FB03) and check the partner data.
  Confirm that the reversal document uses the same or allowed posting partner.
  
  
  
  Adjust the Reversal Posting Partner:
  
  When performing the reversal, ensure that the posting partner entered matches the original document or complies with the partner determination rules.
  If the system automatically picks a posting partner, check if partner determination is correctly set up.
  
  
  
  Review Partner Determination Procedures:
  
  Partner determination procedures might restrict reversal postings.
  Adjust the partner determination procedure if necessary to allow reversals with the required posting partner.
  
  
  
  Check User Exits or BAdIs:
  
  Sometimes custom code (user exits or BAdIs) enforces partner checks.
  Review any custom logic that might block reversal postings with certain partners.
  
  
  
  Consult SAP Notes:
  
  Search SAP Support Portal for notes related to WS898 or partner reversal issues.
  Sometimes patches or corrections are available.
  
  
  
  
  Additional Information:
  
  Message Class WS8 relates to partner functions and partner determination in FI documents.
  Partner reversal restrictions are often in place to maintain data consistency and legal compliance.
  If the posting partner is mandatory for the document type, it must be maintained correctly for both original and reversal documents.
  Partner functions are used to identify business partners like customers, vendors, sales representatives, etc., in FI documents.
