I am trying to link a subreport in Crystal and when I try to preview my results, all I get back is blank spaceholders. I have never created a sub-report before, so it may be something very simple.
In my main report, I have called the PatientVisit.PatientVisitId into the report. In my sub-report coding, I coded the same value and tried linking the two between this common unique field. If the value in the subreport is empty, but a record exists in the main report, I would expect the subreport to suppress on this patient.
Essentially, I could not get SQL to handle what I wanted and I had to go the route of a subreport. Linking them still does not help me it seems.
