Question about incremental refresh (happening in the DataFlow but not in the report)

Dear all, 

 

I have a large table of 50M+ rows in a DataFlow with incremental refresh working. The DataFlow update takes a couple of minutes. 

 

When I import this table from the dataflow into my report and I right click on the last stem, I can see that the "View Native Query" is greyed out. As far as I understand, this might that query folding might not be happening. 

 

After filtering this table using my RangeStart and RangeEnd parameters, I activate the incremental refresh on the table (keep 2 years, update 5 days), but the report update in the server, after the first load, takes a couple of hours every time. So I guess that incremental refresh is not happening in the report update. 

 

Am I missing anything?

 

Thanks in advance

Hi @setis ,

 

Power BI Query Editor cant use Query Folding at all.

Hi @setis ,

 

Power Query loads only data specified between the RangeStart and RangeEnd parameters. Depending on the amount of data in that period, load should go quickly. If it seems slow and process intensive, it's likely the query is not folding.

@Anonymous thanks, but can the folding happen when the source is a PBI DataFlow?

 

The folding is happening in the DataFlow (it's refreshed in minutes), but when the report is refreshed it take a couple of hours.
