Calculate YTD prior month numbers

[dw700d]

I am trying to calculate YTD Prior month spend but something is off

This is the dax measure I am using

---YTD Spend PM = CALCULATE([YTD SPEND],DATEADD('Calendar'[Date],-1,MONTH))---

When I break it down by month the grand total shows the correct prior month spend which is 1580500 but it deletes the month of January and attributes the wrong YTD spend number for July. When I exclude the month then it appears that YTD spend is = YTD prior month spend which is not true.

YTD Prior month spend should be 1580500. What Dax measure can I write to show this?

The chart on the left shows correct YTD numbers, the chart on the right was my attempt to calculate the YTD prior month numbers

Hi @dw700d ,

Create a relationship between your date table and fact table to use time-intelligence-function , create measures like this to get the expected result:

YTD Spend PM =
CALCULATE ( [YTD Speed], DATEADD ( 'Table'[Date], -1, MONTH ) )
