Incremental Refresh Error , Dataset using Folder Connection to .CSV

[nrowey]

I am trying to set up an Incremental refresh for my dataset that is connected to a local folder where the .csv files are added daily.

After setting up parameters  Range Start and Range End Using Type DateTime  I get  Expression.Error: We cannot convert a value of type Binary to type DateTime.
Details: Value=[Binary] Type=[Type]

Is it possable to do incremental refresh to a folder connection to .csv files "datetime" column.

Thanks for any thoughts..

Hi @nrowey ,

1 Check the Data Types: Ensure that the column you’re using for the Range Start and Range End parameters is indeed of DateTime type in your CSV file.

Remember, Incremental Refresh requires DateTime values so you might need to do a bit of casting. I hope this helps! Let me know if you have any other questions.
