I have a Crystal V10 report that uses {appt.start_datetime} = {?StartDate} in the selection formula to pull scheduled appointments. There is a subreport that is linked to the main report by a Patient_id field and ?StartDate to ?Pm-StartDate. I need the subreport to pull all appointments {appt.start_datetime} >= {?Pm-StartDate}. This works however the report takes too long to run. I am hoping it will speed things up if I use a date range in the subreport selection formula to limit the appointments to those scheduled in the next 90 days, roughtly something like {appt.start_datetime} in {?Pm-StartDate} to {?Pm-StartDate}+90 but I can't figure out the formula. Can you help please?
