• What is the cause and solution for SAP error message WS128 - Enter a settlement document type ?

  SAP Error Message:
  
  WS128 - Enter a settlement document type
  
  Cause:
  This error occurs when you are trying to perform a settlement process (such as settling costs from a cost center, internal order, or project) but have not specified the Settlement Document Type in the settlement parameters. The system requires a settlement document type to know how to post the settlement document in Financial Accounting (FI).
  
  Explanation:
  
  In SAP Controlling (CO), when you settle costs from an object (like an internal order or WBS element), the system creates a financial document to post the settlement.
  The Settlement Document Type determines the type of FI document that will be created (e.g., KR for vendor invoice, SA for general ledger document).
  If this document type is missing or not maintained in the settlement profile or settlement rule, the system cannot proceed and throws the WS128 error.
  
  
  Solution:
  
  
  Check Settlement Profile:
  
  Go to transaction OKO7 (Maintain Settlement Profiles).
  Verify that the settlement profile assigned to your controlling object has a valid settlement document type maintained.
  If missing, assign the appropriate settlement document type (e.g., SA, KR, RE).
  
  
  
  Check Settlement Rule:
  
  In the settlement rule of the controlling object (e.g., internal order, WBS element), ensure that the receiver and settlement type are correctly maintained.
  The settlement type should be linked to a settlement profile that has a settlement document type.
  
  
  
  Maintain Document Type in Settlement Profile:
  
  The settlement document type is maintained in the settlement profile under the "Settlement Document" tab.
  Example document types:
  
  SA = General Ledger Document
  KR = Vendor Invoice
  RE = Customer Invoice
  
  
  
  
  
  Re-run Settlement:
  
  After maintaining the settlement document type, re-run the settlement process (e.g., transaction KO88 for internal orders, CJ88 for projects).
  
  
  
  
  Additional Information:
  
  Transaction Codes:
  
  KO88 - Internal Order Settlement
  CJ88 - Project Settlement
  OKO7 - Maintain Settlement Profiles

  Notes:
  
  Always ensure that the settlement document type corresponds to the nature of the settlement (e.g., if settling to a vendor, use KR).
  If you are unsure which document type to use, consult your FI team or SAP configuration consultant.
