RKF and CKF

Hi All,

In my current project, we have a few reports that actually display mostly same items, it's just that the layout is different.

I am thinking to utilize RKF and CKF whenever possible to avoid creating redundant selection in the queries. However, since RKF and CKF are actually sitting outside the query filter, I have hesitation about the performance of this idea.

Any sharing ?

Thanks.
