The perform grouping on server is active.

The probelm I tried to show is:
Does not expect Crystal do smart things for you, you should be careful
on how to write the "Record Filters" and check how the query will be
send to the server.

I had the wrong assumption that Crystal could evaluate it before and
prepare the where clause in accordance with it, it's NOT TRUE.

Simple filters like:
{SalesOrder.SalesManID} = {?SalesManID}

will be correct transformed in a where clause like:
where
SalesOrder.SalesManID = <SomeValue>

the more complexes (envolving formulas, etc.) will not be sent to the
server, even it could be evaluated and choosed between some paterns.

see you !
