Last Week vs This Week and Last Month vs This Month

The first link makes sense. Thanks a ton Greg

1. I have created the measure for Open tickets but how do I showcase only the open tickets for This Week (Monday to Sunday as mentioned above) and Last Week. So the This Week and Last Week should be like a Slicer checkbox so it will show for that week open tickets.

Can you share examples how to use relationships based on the model I have above?

This analysis I have been searching for on the Community since ages though there is a plethora of information never have come across any content that will kind help me show a simple count of tickets based on This Week, Last Week and This Month and Last Month and Tickets open and closed as on Today. I feel if I get this my other analysis would be sorted for sure.

Also below is the screenshot of the measure I have created but how do I know if its based on Created Date or Resolved Date based on my connection Above?

Also to add on to the Thread.

Below is the screenshot of the Incident Table which I import into PowerBi using Import mode.

When I use the below filters and selected Created Date as This Week it takes from 30-08-2021 00:00:00 PST (Monday) to 5th September 23:59:59 (Sunday). So when I run it the count shows 69 and according to my Measure based on Created Date itself it says 77 and now when im checking its 80. Not sure whats the issue. Im sure there is some issue with the measure
