  Certainly! Here's a detailed explanation regarding the SAP error message WS771: "Deviating Tax must be active for settlement party customer":
  
  Error Message: WS771 - Deviating Tax must be active for settlement party customer
  
  
  Cause:
  This error occurs when you are trying to perform a settlement or billing process involving a settlement party customer (e.g., in Contract Accounts Receivable and Payable (FI-CA) or in Sales and Distribution (SD) billing) and the system expects that the "Deviating Tax" indicator is active for that customer, but it is not.
  
  Deviating Tax means that the tax determination for the settlement party customer differs from the main customer or the standard tax procedure.
  The system requires that the settlement party customer master data has the "Deviating Tax" flag set to allow tax calculation based on the settlement party's tax data.
  If this flag is not set, the system cannot correctly determine tax for the settlement party, hence the error.
