DAX Formula

[Anonymous]

Hey y'all, greetings!

I am facing issues developing this DAX formula. My case is that I created one measure like this: Measure A = (SUM(Field A) / SUM(Field B)). It is working pretty well but now, I have to create another measure that returns the (SUM(Measure A) / DISTINCTCOUNT(Field C)). Since I can't sum it, my test gone wrong with this DAX: Measure B = (Measure A / DISTINCTCOUNT(Field C)), I think this example clarifies my idea:

                 A           B           Measure A                 
Sale 1: 27,00     20,00                     1,35
Sale 2: 30,80     70,00                     0,44

Right now, I have to summarize the results of Measure A and divide by Total of Sales.
SHOULD BE: (1,35 + 0,44) / 2 = 0,89
IS DOING:     ((27,00 + 30,80) / (20,00 + 70,00)) / 2 = 0,32

What should be the correct form of my DAX?

Gratefull for your attention!

Hi @Anonymous

i think you should summarize you table

SummarizeTable = SUMMARIZE(Table2;Table2[C];"A";DIVIDE(SUM(Table2[A]);SUM(Table2[B]))) 

... and make you calculation on the summarized table.

Measure = DIVIDE(SUM(SummarizeTable[A]);COUNT(SummarizeTable[C]))

Hi @Anonymous

I'm having a bit of a hard time trying to understand what you need

What is Field C?

What you show (below), is it a table? Measure A is a column of that table??

                 A           B           Measure A                 
Sale 1: 27,00     20,00                     1,35
Sale 2: 30,80     70,00                     0,44

I'm really going out on a limb here but maybe what you need is:

SUMX(Table; [Column A] / [Column B] )  / COUNTROWS(Table)
