  Data Source Changes: If the underlying data source has been modified (e.g., fields added or removed), it may lead to discrepancies in the expected parameters.
  Query Definition Issues: The query might be incorrectly defined, or there may be issues with the filters or variables used in the query.

  Test with Default Values: If the query uses variables, try running the query with default values to see if it executes successfully. This can help identify if the issue is with specific variable values.
  Check Authorizations: Ensure that the user executing the query has the necessary authorizations to access the data and parameters involved.
  Debugging: Use transaction codes like RSRT (Query Monitor) to debug the query and see the exact parameters being passed and where the mismatch occurs.
