Redefined method for CDS-view $count problem

Hi,

I created a service from a CDS view and extended the method to do some additional filtering (mainly on system date which to my understanding is still in development for CDS views).

Now the problem is that if I question the service with a /$count that it returns an incorrect number.

Is my understanding correct that for a $count I need to do a full select on the CDS view, do my logic and then change the count value in ES_RESPONSE_CONTEXT?

Kind regards, Rob Dielemans
