[Please reply ASAP] No result rows on doing data preview on a calculation view using another calculation view as its source

Hello,

I have created a graphical calculation view Z_B (Runs in SQL engine, Data category: cube), on top of another calculation view Z_A (Runs in SQL engine, Data category : cube). Z_A has input parameters with default values. I am not creating any new input parameter in Z_B.

When I do a data preview on top of Z_A, I am able to view result rows. However, when I try doing a data preview on top of Z_B, no result rows are returned.

Any reasons for this vague behavior of calculation view Z_B?

Thanks,

Alston.

P.S: I am using HANA Server version SPS70.
