Rolling weeks next year

[Bart_Breekveldt]

Dear Community,

I want to see certain orders (Amount) for in total 52 weeks, of which three are ahead and one is the current week. For that I made this formula of the rolling weeks. 

=IF(Week([Datefield])>=Week(Date(Today()+28)),IF(WeekYear(Today())=WeekYear([Datefield]),'W-'&Num(Week([Datefield]),00)),IF(Week([Datefield])<Week(Date(Today()+28)),WeekYear(Today())+1&' W-'&Num(Week([Datefield]),00)))

However, W-01 in 2020 doesn't connect with the other data (Amount, Weeks) (and therefore doesn't sort on Max(Datefield)

How can I solve this?

Thanks in advance.

I wrote the accepted solution to an extremely similar situation yesterday.  Have a look and let me know if you still need help adapting to your rolling week and sorting needs.
