Calculate past week sales from last year

User_YQZHD

Hello,

I have a requirement to calculate sales as below

1. Past week in current year
2. Past week in last year

For the 1st one, I was using AGO formula of Ago(Sales,Week,1 )  and it works well.

For the next one, I was trying Ago(Ago(Sales,Year,1 ),week,1) and it fails with error message of

"Nesting of EGO or TODATE functions with differing level argument is not supported" and I see why, since my formula has two levels, YEAR and WEEK. 

Looking for inputs on how we can achieve the 2nd one.

Thanks

Try with this Ago(Sales,Week,52) or may be can be 53 weeks ago.
