DAX calendar with RLS - last 30 days since last data

[ChristoherMuehl]

Hello Community,

We would like to have a date filter (style: between) that displays the last 30 days based on the last date value in the fact table.

It is important to mention that we are using RLS. So for customer A, the most recent row in the fact table is from 05/24, for example, and for customer B it is 05/20.Depending on this, the filter should calculate the 30 days back.

The calendar table is current as follows.
#Calendar = CALENDAR(Min(vImages[Timestamp day]),MAX(vImages[Timestamp day]))

How can we implement this?
You will find a report with sample data here:

Power BI

Thank you in advance!

Hi @ChristoherMuehl,

You can create a two-step filter, first use current username to find out the correspond last date, then use this as filter on calendar table to filter records.

BTW, RLS will apply to different tables based on relationships, you should modify the relationship direction to 'both' to enable filter effects from other tables.
