[Ron1]

I can select anything. Either year or week. or both

[Prashant_Naik]

Hello,

Try this

If(GetSelectedCount(Year)>0,
Sum({<[Week No]={">=$(=Min([Week No])) <=$(=Min([Week No])+14)"}>}Sales),
Sum({<[Week No]={">=$(=Max([Week No])-14) <=$(=Max([Week No]))"}>}Sales)
)

Regards,

Prashant

If I select any week like 3 or 4 in 2019, it has to show last 14 weeks starting from previous year. In your case, that is not happening. 

Let's say I select 1st week of the current year, it has to give trends for last 13 weeks of last year and 1st week of current year

[tresesco]

Create a week sequence field in the script and try like shown in attached sample.

[Kushal_Chawda]

this expression should work

=sum({<Year,[Week No],Year={"$(=max(Year))"},[Week No]={">=$(=max([Week No])-14)<=$(=max([Week No]))"}>}Sales)
