Default value for filters

Relative Date Slicer → set it to Last 2 weeks → every time the report loads, it defaults to that window.

DAX Measure + Filter → create a calculated column like:

IsLast2Weeks = IF([Date] >= TODAY()-14, 1, 0)

Then filter the page/visuals where IsLast2Weeks = 1.

For published reports, you can also use Bookmarks → save a default state (like “last 2 weeks”) and set it as the entry view.

Best practice: use the Relative Date Slicer, it’s built for exactly this use case.
