UNX over SAP BW using relational connection

We have BO 4.0 SP5 Patch 6 and using IDT for universe designing.

My question is whether or not Data Federator handles the single-source relational universe over SAP BW datasource

or DF only handles multi-source universes?  I am using a multiprovider (combines data from 2 infoproviders) as

a data source for my universe.  Is multiprovider considered a mutli-source since it combines data from multiple infoproviders.

I am not trying to combine data from SAP BW and anyother data source which is what multi-source universe does.

Thanks
