What is the difference between refreshing in Power Query Vs. refreshing the Report view

[tamiribas]

After refreshing Power Query and clicking "Load and Apply", Power BI Desktop refreshes the data again.

What is the difference between the two mechanisms?

Thank you

Hello @tamiribas , Hope you are doing good.

When you refresh in Power BI Desktop, the entire report data is updated from the data sources, applying all transformations, and impacting the complete data model and visuals, which is handy when you need the most recent data in your report.

On the other hand, refreshing in Power Query Editor updates only the selected query during the data transformation phase, which is quite useful for testing and validating transformations without affecting the overall data model.

Hi @tamiribas 

Refreshing in Power Query (PQ) refreshes the snapshot that you can work with within the PQ tool. It does not refresh the model itself. Therefore, when you click "Close and Apply," the system runs a refresh of the model/table that you modified.

In contrast, refreshing the front-end interface refreshes the model itself.
