Incremental refresh folding

[Anonymous]

Hello everyone, 

I want to apply incremental refresh. I have set up the parameters RangeStart and RangeEnd, and used these parameters as filters for the table I want to use for incremental refresh. Unfortunately, I have the following message:

I already deleted all the steps in Query Editor: 

Or is it the source which prevents the incremental refresh? 

Secondly, the parameters are not recognized in the Online Service: 

I assume this is correlated with each other, and if one issue is solved, the other issue is solved as well. That's why I included both questions as one. 

Finally, the parameters look like this:

Hello,

What datasource are you using?

You can look at this discussion https://community.fabric.microsoft.com/t5/Desktop/Unable-to-M-query-can-be-folded-incremental-refres...

I am using Exact online, a software package. But I think that it's not possible to use this data source. As you can see, the source is ConnectorExactOnline.Imports("1", 3). That '3' means that you load 3 years of data. So, it doesn't make sense to apply incremental refresh with this data source.

You can still use incremental refresh, using rangestart and rangeend parameters in your M code.

Google, incremental refresh api call

It's a workaround but still you might do the job
