Question about set analysis

[josecanalla]

Hello, I am working with set analysis in Qlik sense.

I have this expression: SUM({BM} field) where BM is a bookmark.

This expression is not modified if I do any selections in the app. I want that the expression will modify if I do selections in only one special field of the app... how can I do this?

Thanks!

May be this

SUM({$*BM} field)

No, that modifies the expression if I select anything in the app. I want to modify the expression only if I have selections in special field...

May be this

Sum({BM<SpecialField = $::SpecialField>} field)

or

Sum({BM<SpecialField = p(SpecialField)>} field)
