Hi everyone,
I want to sum hours only once per id using dax.
For example, in this table above the expected result of the measure will be 89 : 27(id1) + 30(id2) +30(id3) + 2(id4)
The summarize function with sumx should be avoided because my original table has much more than one million rows and I think will be very slow with this approach.
Can you help?
Thank you very much for your time.
| id | hours |
| 1 | 27 |
| 2 | 30 |
| 2 | 30 |
| 3 | 30 |
| 3 | 30 |
| 3 | 30 |
| 3 | 30 |
| 4 | 2 |
Solved! Go to Solution.
@marijane , summarize or values are the options you can use
Try values with sumx
sumx(Values(Table[ID]), calculate(max(Table[Hour])))
i love you.
