Passing an input parameter through decision table

Hello there,

I have stumbled upon an interesting requirement:

I need to pass an input parameter through a decision table. We have defined our data models to contain a decision table to achieve "user friendly" filtering.

Now I need to do a calculation based on an input parameter in a view that is "before" this decision table. Is there a way how to pass an input parameter through a decision table?

Thanks a lot, Milos.
