  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.
  Reversing only one document breaks this logical link and can cause data inconsistencies.
  
  
  Solution:
  To resolve this error, you need to reverse the entire supplier settlement list or handle the reversal at the list level rather than at the individual document level.
  Steps to solve:
  
  
  Reverse the entire settlement list:
  
  Use the transaction or program that allows reversal of the whole supplier settlement list.
  For example, use transaction MRRL (Release Blocked Invoices) or MRRL related to settlement reversal, or the specific settlement list reversal transaction depending on your SAP version and configuration.
  
  
  
  Check the settlement list status:
  
  Ensure the settlement list is not already reversed or partially reversed.
  If partially reversed, you may need to reverse the entire list and then reprocess.
  
  
  
  Consult with FI/CO team:
  
  Since settlement documents affect accounting, coordinate with your Finance (FI) and Controlling (CO) teams to ensure proper handling.
  
  
  
  Use SAP Notes or Support:
  
  If standard reversal options are not available, check SAP Notes or contact SAP Support for guidance.

  Transaction Codes:
  
  MRRL - Release Blocked Invoices (sometimes used in settlement processes)
  MRBR - Release Blocked Invoices (related)
  MRKO - Settle Consignment/Return Deliveries
  MRKO or other settlement transactions might be used depending on the scenario.
  
  
  
  SAP Modules Involved:
  
  MM (Materials Management)
  FI (Financial Accounting)
  CO (Controlling)
  
  
  
  SAP Notes:
  
  Check SAP Notes related to settlement document reversal restrictions.
  Example: SAP Note 123456 (hypothetical) might describe this behavior.

  Summary:
  
  Cause: Attempting to reverse a single settlement document from a supplier settlement list is not allowed because these documents are linked.
  Solution: Reverse the entire supplier settlement list or handle reversal at the list level.
  Advice: Coordinate with FI/CO teams and use appropriate SAP transactions or tools for reversal.
