Comparison of the same periods (NOT YTD)

[zototo]

Hi everyone, 

Hopefully, you can help. I have a table where I need to have the following columns:

Previous Week Actual CY (current year) | Previous Week Actual LY (last year). 

For the current year, there's no problem, it's fine (I have a master calendar):

sum({<Year={"$(=Year(Max(Date)))"}, WeeksAgo = {1}>} Actual)

But for the previous Year Week it's a headache. All the related topics are based on YTD data and I could not find anything to help me. 

Looking forward to your support:)

Thank you!

Sounds like you'd want to create a flag for this as well, perhaps something along the lines of:

If(Weekname(AddYears(Today()-7,-1)) = Weekname(AddYears(Date-7,-1)),1,0 as LYWeeksAgo

// Do note that this will return the last week of the previous year in case of week 1, if you want to avoid that you'd need to add a condition

I assume that you use the WeekYear as dimension - which would prevent to display the data of another year. In this case just replace the WeekYear with the Week (maybe as horizontal dimension) and add Year as vertical dimension and then using something like sum(Value) as expression.
