Subtracting row from previous row to get current row
I need a DAX to calculate the following....
The DAX for Change
= Orginal QTD (using total by quarter measure) - Current QTD(using total by quarter measure)
I have a Values column which is the Monthly goal total. I need to work my way backwards from the example of 2603 and minus the quarterly change EX: 0 to get the row above it(2603). For the next row, minus $25 from $2603 etc... The tricky part is the 2603 is the total of a different column.
So if I have
Quarter Change Calculation
2 2021 0 2603
4 2021 63 2578
1 2022 33 2515
2 2022 56 2482
3 2022 0 2426
I hope that makes sense!
Try this ...
Use Power query to derive a date from the quarter. Either the first date or the last dfate of th quater will suffice.
Then relate date to a standard Calendar table which has a quater offset column
Then create measure using offsets ....
This quarter value = CALCULATE( SUM(table[value], DimCalandar[quarteroffset= 0)
Previous quarter value = CALCULATE( SUM(table[value], DimCalandar[quarteroffset= -1)
Difference = [This quarter value] - [Previous quarter value] =

If you give someone a fish then you only give them one meal, but if you teach them how to fish then they can feed themselves and teach others for a lifetime. I prefer to teach members on this forum techniques rather give full solutions and do their job. You can then adapt the technique for your solution, learn some DAX skills for next time and soon become a Power BI Super User like me.
