Partial Data-source Refresh

[zbareta]

Hi everyone!

I have a report where I am pulling data from multiple data sources.

Most of this is fine, as I am getting data from the web (kobo toolbox), from 9 data-sources (all formated similarly and appended). Everything refreshes normaly.

The problem is that i also have several .XLS data sources (also formatted and appended ) that work fine in BI Desktop, but there is a problem when refreshing the dataset through the service.

This .XLS data does not need to be refreshed. They are old back-up files that are useful in terms of statistics and vizualisation, but that are never updated. 

I can't "enter" the data directly into BI Desktop (too many columns), nor can i upload it as a dataset to the BI service (it does not allow me to create reports with BI service data and other live data).

As it is impossible to "tell" the service only to update data collected from the web, and leave the .xls files alone (do not refresh), what would be your proposal on solving this in terms of best practice.

Move the .XLS to OneDrive, Sharepoint, Dropbox...? Is there something more obvious that I am missing?

Thank you in advance!

Hi Zeljko,

There is a new feature under preview called "Incremental refresh". Surely it has some limitations for now. I wounder if it could help in your scenario. You can give it a try. Please refer to power-bi-desktop-may-2018-feature-summary/#incrementalRefresh.

Hi, I don't know if t his thread is still going, but to my knowledge Power BI service does not allow the refresh of .XLS files on a schedule, just via  refresh and publish in the desktop app.  that said, it is possible to remove a table from a report refresh: 

you right click on the table in query editor and untick "Include in report refresh" that way the data remains static and the refresh skips that table

Thanks so much for this answer! Incremental refreshes would not work for me since I have a data source that is no longer functioning

Hi there

I think that even if the file is part of the desktop file it would want it to be connected to the Gateway?

Hi @zbareta,

@v-jiascu-msft is correct, you can use this feature and I suggest you concentrate on Detect data changes part:

Inremental refresh

Be aware that it is applicable for all Power BI Premium and Power BI Embedded capacities (starting from A3).

Hi there

Currently Power BI will refresh all the data in the model and there is no way to only refresh selected data.
