Period Rolling Turnover by Employment Category

Summary: I am trying to get a rolling turnover by employment category. This analysis doesn't change any value even if I provide the assignment category filter. The result for any assignment category is the same. Where can I use this filter in the analysis to reflect correct turnover per employment category?

FYI- My dashboard prompt is using the employment category from Assignment Realtime subject area. While trend has assignment category. So I have joined the Realtime subject area as well.

Thanks,

Anita
