Looking for Solutions: Date Filter Not Functioning with M Query Parameter

Problem: M Query Parameters in DirectQuery filter data before it reaches Power BI, so standard slicers or DAX columns won’t work properly.

Solutions:

Separate Date Table + Relationship – Use a Date table not bound to the parameter; slicer filters fact table via relationship.

Start/End Date Parameters – Fetch only a date range via two parameters; users select dates via parameter UI.

Load All Dates – If dataset is small, remove parameter and use normal slicer.

Searchable Date Dropdown – Create a distinct date lookup table; use a slicer with search enabled for user-friendly selection.

Recommended: Use parameter to limit range + separate searchable Date table for efficient filtering.
