Hi,
I have question about YTD Last year DAX formula. Even though I have read many blogs and topics here in community, I still don't know how to solve this issue.
Suppose I have data like below.
| ID | Date | Amount |
| 1 | 01.01.2016 | 10 |
| 2 | 02.01.2016 | 15 |
| 3 | 03.01.2016 | 11 |
| 4 | 10.01.2016 | 8 |
| 5 | 20.02.2016 | 7 |
| 6 | 01.01.2017 | 10 |
| 7 | 02.01.2017 | 12 |
| 8 | 03.01.2017 | 9 |
I would like to figure up YTD value of amount for actual data (year 2017) and then YTD value for corresponding period previous year.
For YTD I use formula:
YTD = CALCULATE(SUM(Data[Amount]);DATESYTD(Date[Date]))
For YTD LY I use formula:
YTD LY = CALCULATE([YTD];SAMEPERIODLASTYEAR(Date[Date]))
Then when I use these formulas in PBI, I have got incorrect value for YTD LY. I expect value 36 (dates: 1.1. - 3.1. 2016), but in total I have got 44 (it also calculates Amount 8 in 10.1.2016) - so it gives me period of january 2016, but I want only the corresponding days from 2017.
But YTD LY value in pic below on row for 3.1.2017 is OK.

Does anybody know the solution?
Thanks.
Regards.
