I have a challenge on a Specific DAX formula.
I have one tabel containing A CustomerID, Week and a Value. I would like to add a Calculated Collumn that sums the Value of the Specific Customer in the Same Week.
It should look like the result below;
Cust | Week | Value | SUM
A | 1 | 2,5 | 6,5
A | 1 | 4 | 6,5
A | 2 | 2,5 | 5
A | 2 | 2,5 | 5
B | 1 | 5 | 6
B | 1 | 2 | 6
B | 2 | 5 | 10
B | 2 | 5 | 10
C | 1 | 8 | 8
C | 2 | 8 | 8
C | 3 | 8 | 8
C | 4 | 8 | 8
I've treid using CALCULATE, SUM and SUMX but i wasn't albe to create the above results.
I've also read different items on the "SUMIF" function but i couldn't find a way of sum that checks 2 identifying collumns (Cust. and Week)
I hope that someone could help me on this matter?
