SamePeriodLastYear is blank

[AJ007]

I have a dataset with column for years and another column for unemployment rate. I want to calculate the difference year over year. I tried SamePeriodLastYear but it's giving me blank output.

I have done lots of tricks to get a dates column as the original dataset didn't have a dates column but only the years column.

Please help.

Assuming you have a year column and a value column

this year = sum(table[value])

last year = calculate([this year],filter(all(table[year]),table[year]=max(table[year))-1))

Sorry it didn't work.

This is my test data

It works for me.  Note there was one wtone shaped bracket in the orginal formula I posted
