Can I use a relation in TypeDB(formerly Grakn) several times?

I'm putting up my TypeDB schema and I have the entity problem which is caused by many different things, e.g. by a certain practice or a certain factor.

I specified the relation causing like:

 causing sub relation, 
   relates causer, 
   relates caused,

I don't see in the documentation whether now both entities practice AND factor can play the role causer. It would be great if someone could answer this or point me to a more extensive documentation TypeDB or even an extensive example.

The relationship roles that each entity can play are defined on the entity definitions themselves.

So, if you wanted both practice and factor entities to play 'causer' you would define:

practice plays causing:causer;
factor plays causing:causer;

Here is the documentation on role definitions: https://docs.vaticle.com/docs/schema/concepts#entity-to-play-a-role
