DAX SUM of Measure by row with correct Grand Total - then multiply by 0.10

[Anonymous]

Greetings,

   I have the formula below stuffed in to a measure because I wanted the count to be evaluated by row. 

COUNTAX(DISTINCT(LY_SS_REF[CUSTOMER_NUMBER]),LY_SS_REF[CUSTOMER_NUMBER])

   I'm trying to get the SUM value of said measure but need to ensure the Grand Totals are correct and then I want to multiply that number (by row) by 0.10.  I've tried every configuration I can think of, have read Greg Deckler's posts and videos but nothing's clicking and I believe I've made more of a mess than anything else.

   Here's what I've got.

Distinct # of SSIncrease2:=SUMX(LY_SS_REF,COUNTAX(DISTINCT(LY_SS_REF[CUSTOMER_NUMBER]),LY_SS_REF[CUSTOMER_NUMBER])*.1)

   Assistance/Wisdom is much appreciated. 🙂

@Anonymous , Try like

Distinct # of SSIncrease2:=SUMX(Values(LY_SS_REF[CUSTOMER_NUMBER]),calculate(COUNTAX(values(LY_SS_REF[CUSTOMER_NUMBER]),LY_SS_REF[CUSTOMER_NUMBER]))*.1)
