Count of Calculated Measure in front end in Qlik Sense

[rajeshwar1]

I have a cumulative percentage calculated measure in front end. 

I have wrote an expression:

if((num(rangesum(above(num(count({<[CB_tra_cur.DEBITMEMO_check]={'Y'},[CB_tra_cur.Final_Max_EXTERNALPAIDDATE0]={">=$(vPrev1ExtStartDate) <$(vPrev1monthExtEnddate)"}>}distinct CB_tra_cur.DEBITMEMO)),0,RowNo()))

/

sum(total aggr(count ({<[CB_tra_cur.DEBITMEMO_check]={'Y'},[CB_tra_cur.Final_Max_EXTERNALPAIDDATE0]={">=$(vPrev1ExtStartDate) <$(vPrev1monthExtEnddate)"}>}distinct CB_tra_cur.DEBITMEMO),[CB_tra_cur.Ageing Bucket_cre])),'#0%')

)>=0.92 ,'A','B')

now I want to count how many A and How many B are there .

Please Help
