App Structure proposal

[Ralino]

Hi Dears

Planning to build an app to get result based on big multiple calculation considering multiple selection as inputs.

Considering i have Onedrive for business as well as Sharepoint and Powerapp.

What is the best way please to structure the app? thinking about, getting data source from One drive, selection in Sharepoint and do calculation in Power app then having result in sharepoint.

Is this the best way, will it work, is there another smarter way?

Thanks

Hi @Ralino ,

Why do you use multiple data sources within your app?

Based on the needs that you mentioned, I think it is not necessary to add multiple data source in your app, I think SP List data source is enough.

In addition, the Excel table data source is a inherently slow data sources, it has a lower performance within PowerApps app than SP List.

More details about the difference between Excel table and SP List, please check the following article:

As a better way, please consider add SP List data soure in your app rather than the combination of Excel table and SP List data source.

Best regards,
