Multiple Time Dimensions in a cube

I have a fact table that includes multiple date fields OrderEntryDateId, WantDateId, ShippedDateId, InvoicedDateId.

Can I join time to more than one field or do I need to create 4 different cubes?

Thanks,

Chris

Hello. Provided that you have the same keys in the time dimensions table as for each date in your fact table, you can use this single time dimension for all time keys in the fact table.

You design the relations(primary key and foreign key) in the data source view, that you create before the cube.

When you build your cube i BI-Dev Studio, with the wizard, it will take care of creating different cube time dimensions for each fact table date field.

So one time dimension table will work in SSAS2005.

I am using SSAS2000. Does this mean I need to upgrade? I don't see a way to do this in 2000.

Hello. In SSAS2000 you will have to build views in order to clone your original time dimension. Each time view will have to be joined to the fact table.

Upgrade or not? This depends. Some day you will have to.

Role playing dimensions(that i have decribed to you) is not the most important feature in SSA2005.

Are you saying to make a view in SQL Server, or is this something that is done in SSAS 2000.

Thanks

Hello again.

With SSAS2000 you will have to build the view in SQL Server.
