Is there any problem creating a Expression less extension?

[#1]

Hi all..

I'm trying to build a Expression less extension. That is, that I only have dimensions (in fact, multiple dimensios).

But there is no data coming for QV. Not even the headears are coming.

Did any one try this before??

In fact, is there any problem doing this??

If I add at least one Expression, this start to work again.

Extensions are essentially straight tables, so they need an expression.  The easiest way to do this is just set the expression to =1
