  Test with Sample Data: Run the MDX query with a smaller dataset or sample data to isolate the issue. This can help identify if the problem is with specific data points.
  Review Model Configuration: Check the configuration of the InfoObjects and InfoProviders in SAP BW to ensure they are set up correctly and that the data types align with the expected values.
