Datamart increase cache

[PowerBITestingG]

Hi all,

I am using a dataflow as source for my datamart, whenever I try to activate incremental refresh for the datamart (the dataflow has it), I get an error telling me to increase cache size

I am not able to find where this increase cache size option is, I assume is similar to the desktop option?

I am getting this on Power BI Service. 
Steps:
Create Data Mart
Get Data (Excel from OneDrive. ~488MB)
Transform Data.  (Change a few field types).  Then Save and I get this error:

Loading Data

Error Message PipelineException: The evaluation reached the allowed cache entry size limit. Try increasing the allowed cache size.

Are you connecting to any other data source in the datamart besides the dataflow? And are you using the data gateway (which is not needed between a datamart and a dataflow)?

I am just connecting to the dataflow. It loads well. Then I try activating the incremental refresh and I get the error
