Problems linking dimension tables and fact tables in SSAS cube

Problems linking dimension tables and fact tables in SSAS cube

Problems linking dimension tables and fact tables in SSAS cube


I have a problem with SSAS trying to relate tables.

I have this tables:

1) hc_routes (airplanes routes):

id_route, id_aeroline, id_airport_source, id_airport_destination
PK: id_route

2) co_route_equipments (planes of each route)

id_route, id_equipments
PK: id_route, id_equipments (I have N equipments for each id_route)

3) dm_equipments

id_equipment, desc_equipment
PK: id_equipment

4) dm_airport
id_airport, ....(atributes)
PK: id_airport

5) dm_aeroline
id_aeroline, ....(atributes)
P‌K: id_aeroline

I have made a data source and a cube with this tables. I define metrics for hc_routes y co_route_equipments
(count of routes).
In the 'dimension usage' I can link:
- hc_routes with dm_airpors and dm_aeroline
- co_route_equipments with dm_equipments

I would like to relate dm_equipments with hc_routes but I don't know how...
I want to count how many routes has a equipment, but filtering by airport or airline then
I need to use hc_routes

The relation needed is:

d‌m_equipment - (id_equipment) 1:N -> co_route_equipment ->(id_route) 1: 1 -> hc_routes‌

Any advice will be greatly appreciated
