Slicer help - filter events based on another time period/connection type

[ericperez92]

I have two tables:

1. a table that records when a device's radio connection changes
2. a table that records when an application is opened on a device

Ultimately I want to know which applications were opened during a certain radio connection type. Ex: show all applications used during a "cellular" connection time period. I would like to have a slicer for the connection type that filters both tables.

I have an example of the records I am using along with an example of the data model. I tried to show how I expect the results to be filtered.

Should I add a custom column using dax in the application table that looks up what connection was being used by the device when the application was opened? Or should I have the connection type recorded along with application name in application table from the source? Then use a slicer with connection type from the application table?

Any help or recommendations on solving this is much appreciated! Thank you!

Hi  @ericperez92 ,

Here are the steps you can follow：

1. Create measure.

Measure =
CALCULATE(MAX('Applications Table'[Application Name]),FILTER('Applications Table',
'Applications Table'[TimeStamp]>=MAX('Connection Table'[TimeStamp])
&&
'Applications Table'[TimeStamp]<=MAX('Connection Table'[Next Timestamp])
))

2. Result

You can downloaded PBIX file from here.
