Filter data by function into related table

Hi all, i'm a novice of qlik sense, I would like to create a new app but I've got some problems with filters.... I need to create a filter like this:

Table User => Table Post

I need to filter NEW users or OLD users by a selected date (selected in another filter).

NEW users are all people that in that selected year had insert their first post.
OLD users are all people that in that selected year had insert a post, but they had insert a post even in previous years.

in sql table are :


USER:
id

name

POST:

id
userId
insertDate

Have you got any idea?

Thanks

M.
