Incremental refresh not working

Hi akasthan 

The warning that "Unable to confirm if the M query can be folded. It is not recommended to use incremental refresh with non-foldable queries." doesn't means your data source couldn't set incremental refresh. This warns you that your data source doesn't support query fold, incremental refresh may not have a good performance when refresh. 

Can you refresh your report successfully?

Is your problem that your refresh is successful but you couldn't find the latest value?

Here is a blog about setting incremental refresh for Azure Data Lake Storage.

For reference:

Parquet, ADLS Gen2, ETL, and Incremental Refresh in one Power BI Dataset

Please check your data/time parameter.

Cannot set up incremental refresh
