KO189 - Details

• The SAP error message KO189, which states "Settlement fields cannot be changed at this time," typically occurs in the context of controlling (CO) and project systems (PS) when you attempt to modify settlement-related fields for a cost object (like an internal order, project, or cost center) that is already in a certain status or has been settled.
  Causes:
  
  Settlement Status: The cost object may have already been settled, meaning that the settlement process has been completed, and changes to settlement fields are not allowed.
  Document Status: The associated documents (like purchase orders, invoices, etc.) may be in a status that prevents changes to settlement fields.
  Period Lock: The financial period may be closed, preventing any changes to the cost object.
  Authorization Issues: The user may not have the necessary authorizations to make changes to the settlement fields.
  
  Solutions:
  
  Check Settlement Status: Verify if the cost object has been settled. If it has, you may need to reverse
