Field Parameter appear as count

Hi ahmedshalabyy12 ,

this is most likely due to field parameters not being supported with a live connection to a semantic model (SSAS/Analysis Services). When you use a live connection, Power BI can’t evaluate the dynamic field parameter the same way as in an imported dataset, so the visual ends up showing a default aggregation like Count.

What you can try or consider:

If possible, switch to an imported Power BI dataset (or publish a Power BI dataset) instead of using a live SSAS connection. Field parameters work in that scenario.

If you must stay with a live semantic model, field parameters are not reliable for dynamic measure switching. In that case you have two workarounds:

Implement the dynamic measure logic on the server side (in the semantic model) using pre-defined measures and a slicer (DISCONNECTED parameter table) that maps to those measures. Note: this requires you to modify the semantic model itself.

Use separate measures in the report (Sum, Avg, Count) and provide a manual way to switch visuals via bookmarks or a slicer, but this won’t be a true field parameter switch in real-time.

Check the datatype of the field parameter column in the semantic model. A mismatch (e.g., numeric vs text) can cause odd behavior. If you can, ensure the parameter column is a text/string type and that the parameter table is properly designed for a field parameter.

Please mark this post as solution if it helps you. Appreciate Kudos.
