  Meaning / Cause:
  This error occurs in SAP BusinessObjects Web Intelligence (WebI) when a service definition contains a parameter that references a function which is not recognized or does not exist in the system. Essentially, the WebI report or service is trying to use a function that the platform cannot identify, possibly due to:
  
  A mismatch between the WebI report and the BI platform version.
  Corrupted or outdated service definitions.
  Custom functions or extensions that are missing or not properly deployed.
  Incompatibility after a system upgrade or patch.
  Incorrect or incomplete configuration of the WebI service or its parameters.
  
  Detailed Explanation:
  
  Service Definition &1: The name of the service definition (e.g., a WebI service or a report service).
  Parameter &2: The specific parameter within the service definition that is causing the issue.
