Calculation View Currency Conversion with BW on HANA

Experts,

We are on BW 7.5, HANA SP11.

I have a calculation view based on a generated analytic view from a BW cube.

When I try to use currency conversion in HANA calculation view, the "schema for currency conversion" does not show the BW schema i.e SAP"SID" to use the TCUR* tables. Is it an authorization issue? How can I use the BW TCUR* table to perform currency conversion in HANA?

Any hints is well appreciated.

Thanks and Regards,

Srinivas
