• What is the cause and solution for SAP error message WS163 - Document &1 can only be maintained via the supplier settlement list &2 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WS163 Document &1 can only be maintained via the supplier settlement list &2
  
  Cause:
  This error occurs when you try to directly change or maintain a document (usually an invoice or credit memo) that is linked to a supplier settlement process, but the system restricts such changes. The document is controlled by the supplier settlement list (also called the supplier settlement run or settlement document), and direct maintenance is not allowed to ensure data consistency and integrity.
  In other words, the document &1 (e.g., an invoice number) is part of a supplier settlement list &2 (e.g., a settlement run number), and SAP enforces that any changes to this document must be done through the supplier settlement list, not directly.
  
  When does this happen?
  
  When you try to manually change or delete an invoice or credit memo that has already been included in a supplier settlement run.
  When the document is locked for direct editing because it is part of a settlement process.
  This is common in scenarios involving supplier invoice settlement in SAP Materials Management (MM) or Logistics Invoice Verification (LIV).
  
  
  Solution:
  
  
  Do not change the document directly.
  
  Instead, you must process changes via the supplier settlement list.
  
  
  Use the supplier settlement transaction to make changes:  
  
  Go to the transaction for supplier settlement (e.g., MRRL - Evaluated Receipt Settlement, or the relevant settlement transaction in your system).
  Find the supplier settlement list &2.
  Make the necessary changes or reverse the settlement from there.
  
  
  
  If you need to correct the document:  
  
  Reverse or cancel the settlement run for the supplier settlement list &2.
  Make the required changes to the document &1.
  Run the supplier settlement again.
  
  
  
  Check authorization and process flow:  
  
  Ensure you have the correct authorization to perform supplier settlement.
  Follow the standard process for supplier invoice settlement to avoid inconsistencies.

  Summary:

To resolve this, you must make changes through the supplier settlement process, typically by reversing or adjusting the settlement list and then reprocessing it.
