Rankx Not working as expected when data is filtered using slicers and filter pane

Hi Vivek26 

Please check this measure. Although it is not concise enough, it seems to meet your requirements.

rank = 
var currentDistrict = SELECTEDVALUE(Store[District])
var sumTable = SUMMARIZE(ALLSELECTED(Store),Store[Region],Store[District],"Total_Amount",[Total Sales])
var rankTable = ADDCOLUMNS(sumTable,"Rank_Value",RANK(DENSE,sumTable,ORDERBY([Total_Amount],DESC)))
return
MAXX(FILTER(rankTable,[District] = currentDistrict),[Rank_Value])

I struggled a lot but haven't figured out a method with RANKX yet. Hope this would be helpful. 

Best Regards,
Jing
