  SAP Error Message:
  WS855 - Single reversal of settlement docs from supplier settlement lists not allowed
  
  
  Cause:
  This error occurs when you try to reverse a single settlement document that was created as part of a supplier settlement list. In SAP, settlement documents generated from supplier settlement lists are linked and managed collectively. The system does not allow reversing just one document from such a group because it could lead to inconsistencies in the settlement process and accounting.
  In other words, the settlement documents are part of a batch or list, and reversing only one document from that batch is not permitted.
  
  Explanation:
  
  Supplier Settlement List: A collection of settlement documents created for a supplier, often generated during periodic settlement runs.
  Settlement Document: The accounting document created to settle costs or invoices.
  When these documents are created as part of a list, they are logically linked.
