Above script i have join like DATE_KEY=DATE_KEY

Now my question

In my report i have prompt (Distributed Date and Approved Date)

When i select Distributed date in my prompt then my join should be

Fact.DISTRIBUTED_DT=DIM.DATE_KEy

When i select Approved Date in my prompt my join should be

Fact.APPROVED_DT=DIM.DATE_KEy

How can i achieve this.Some time Distributed date join and some time Approved date join.

Can you please help
