Sameperiodlastyear and Dateadd not giving correct result

[lekkerbek]

Hi all,

I hope someone can help me. I know what the problem is, but I don't know how to solve it.

I have a situation where there are 13 periods in a year. The data that is imported is not on a daily basis, but imported on the last day of that period through an Excel file. So what I have for example is:

data on 26 January 2020

data on 24 January 2021

If I choose sameperiodlastyear or dateadd -1 year to compare it shows blanks. Obviously because it compares 24 January 2021 to 24 January 2020 (which has no data).

Is there a way to work around this?

@amitchandak thank you very much. That was it!

@lekkerbek , I think you need 364 day behind year 28*13

example

Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-364,Day))

make sure you use date table
