Indirect Dimension Selection

[joey_lutes]

I'm in the process of building a dashboard report that works nearly only with dimensions in Qlik Sense 2.2.3.

Through the process, I need the ability to display indirect selections within a straight table of data.  Here is simplified example:

Service          Site          SiteType

A                    1                Aux

A                    3                Key

B                    2                Aux  

B                    3                Key

C                    1                Aux

C                    6                Aux

C                    7                Key

Suffice to say that Service A is available at Sites 1 and 3 etc. 

My intent would be to have a user select a (multiple) Site - Site 1.

As Site one is selected, possible services are A and C.

I need to show that Indirectly, Sites 1, 3, 6 and 7 are tied to those services.

Furthermore, for services A and C, I want to identify the Key site associated with each (in this case, sites 3 and 7 respectively).

I believe from what I've gleaned from Indirect Record Selection

that this is possible using {p}, though my attempts thus far have failed.

Thoughts/ideas?

Thank you

I guess add Site as your dimension and this as your expression -> Only({<Site = , Service = p(Service)>} Service)

My bad, you would need to add Site and Service as dimensions and may be use this as your expression-> Only({<Site = , Service = p(Service)>} SiteType)
