Turning On and Off Calculations in Power BI Visuals

Phil Seamark has a clever workaround:

Power BI doesn’t yet have a feature that allows end-users to turn on/off the ability to process calculations for visuals on a report page until they are ready. Most of the time, this is perfectly fine – however, in some instances, it can be handy to disable long-running and heavy calculations from running. At the same time filters/slicers are get selected.

The scenario you most likely want to have this control is when your model uses Direct Query mode against large tables in data sources that charge you for query processing. Even if your Direct Query data source does not charge per query, having a user make quick-fire selections over several slicers can potentially saturate a back-end data-source and unnecessarily chew up resources.

Read on to understand how to use calculation groups to do this, as well as the limitations around this solution.
