  Validate Node Configuration: Inspect the configuration of the node in the DMEE tree. Make sure that the data type specified for the node aligns with the data being processed.
  Data Type Adjustment: If necessary, adjust the data type of the node or modify the incoming data to ensure compatibility with the conversion rules.
  Test with Sample Data: Use sample data that matches the expected format to test the DMEE configuration. This can help identify if the issue is with the data or the configuration.
  Debugging: If the issue persists, consider using debugging tools within SAP to trace the data flow and identify where the mismatch occurs.
