Cascading Parameters Not Auto-Refreshing After Multi-Select in PowerBI Report Builder

Hi Chetan40 , Thank you for reaching out to the Microsoft Community Forum.

This is expected behaviour in Report Builder / SSRS and is effectively by design. Cascading parameters only refresh after the parent parameter value is committed, not while the multi-select dropdown is still open. In multi-select scenarios, the selection isn’t applied until the dropdown loses focus, for example, when the user clicks outside, which is when the dependent parameter query is triggered.

There is no native way to force real-time refresh while the dropdown is open. Power BI Paginated Reports behave the same way since they use the same underlying SSRS (RDL) parameter framework. The usual approach is to guide users to close the dropdown after making selections or simplify cascading dependencies where possible to reduce interaction friction.
