I am using star Schema model , with all the fields  on UI in different

dimension table

Filter drop down -visit name
Filter drop down -SP
Filter drop down -Protocol

I have 3 columns on UI -Protocol,visit_name,SP
i need to calculate two measures

Measure 1- Calculate total Patient count , based on protocol & SP

Measure 2- Calculate total Patient count , based on protocol & SP & visit name -This is easier as all 3 columns are on UI

Challenge is Calculate total count for measure 1 which is based on two columns

If i write set expression and use total formula ignoring visit name columns then on top of page I have 3 filters it ignores the filter i made for visit as well

expr-count({<visit_name>} distinct total <Protocol,SP> Patient)
But because of this expr my filters selection made in visit doesn't show filtered data on grid.

Protocol	visit_name	SP	Patient	calculate count=>no_of_Patients- based on  SP & Protocol)	count =>no_of_Patients-no_of_Patients based on-> SP & visit & Protocol
11	wk1	Malaria	A	5	2
11	wk2	Malaria	A	5	1
12	wk5	Malaria	B	5	1
11	wk1	Malaria	A	5	2
11	Wk3	Malaria	A	5	1
11	Wk1	Dengue	A	1	1
12	wk5	Dengue	B	1	1
