Total of the month not corresponding to the total of the values of the single days

[alecsonline]

Hi all!

I have 2 measures that are total of values from 2 different tables: "RMS DW" and "RMS cfd lettura"

No problems with them: correct values and totals....everything fine.

I created a new measure:

Measure = IF([RMS DW]=0;[RMS cfd lettura];[RMS DW])

My goal is: "If that are no values in RMS DW than take into consideration the "RMS cfd lettura" otherwise use the "RMS DW" values.

THE STRANGE THING: this measure gives correct values day by day, but the month total is not correct!!!! How is it possible?

Look at the table below: last column shows exactely what I want day by day, but you can see the total says "310" that is only the total of the first 5 rows!

Any idea about what's wrong?

Thank you all, Alessandro.

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376
