Microsoft Fabric Data Engineer Associate DP-700 Practice Question

A Fabric dataflow that combines multiple CSV files in OneLake fails to refresh and returns the error "Expression.Error: The column 'TransactionDate' of the table wasn't found." In Power Query Online you confirm the Source step lists TransactionDate, but the automatically generated Replace Errors step is hard-coded to the original three-column layout. Several newer CSV files now include an extra column at the start of each row. To ensure future refreshes succeed without manual edits, what should you do?

  • Reschedule the dataflow to refresh during off-peak hours to reduce contention.

  • Enable incremental refresh on the dataflow and filter by TransactionDate.

  • Convert the TransactionDate column's data type from Date/Time to Date in the Changed Type step.

  • Delete the existing Replace Errors step and add a new one that uses dynamic column names, or remove it if it is not required.
