BW on HANA architecture with multiple ECC sources

Hi All,

Can you please help me in understanding a BW on HANA architecture where the client has 5 ECC sources which might increase in the future.

I need to understand how the architecture would look like &  how we will consolidate the data in BW.

Also if we have HANA Studio license, how can we do this consolidation with SLT or BODS.

Please help.

Thanks,

Sam
