Custom table is not working when filtering on date

Hi Jack00711, you don't need to build a calculated table for this case. Calculated table is refreshed once, when your semantic model is refreshed. Therefore, any further interaction with slicers won't change it.

If you already have a classic data model like this, the only thing you need to do is to apply a filter on "Date" column from "Calendar" table, it will filter the fact table accordingly.

Then you create DAX measure that will show you data for all fields selected before the current date, but when using data in slicer visual there is an easier way:

You can find sample pbix attached.

Good luck with your project 🙂
