IDT Multi-source excel universe

Hi All,

I am trying to create a universe based on excel spreadsheets. There are 3 excel spreadsheets, E1 and E2 are in folder A and E3 is in folder B. I am creating this universe as multisource universe. I created 2 odbc connections. Connection 1 using folder A spreadsheets and Connection 2 using folder B spreadsheets.

Connection in the universe works fine. If I create a data foundation using one connection it works fine but when I create data foundation using multi source, it gives error as:

[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.

What is the issue?How do I resolve this?

Thanks,

Nisha
