You should be able to display the PDF directly

Create a new report
Unless you need data for something click OK on the data screen
Click INSERT --> OLE OBJECT
Choose Adobe Acrobat Document from the drop down
Navigate to the file
Select the file
Click OPEN
Insert where you want it
Size it to fit the page

Since the report is generated dynamically.  The PDF is also different every time.
The report does not seem to refresh with new PDF content. It displays the content that was loaded when I inserted the OLE OBJECT.
How do I refresh the content after changing the underlaying PDF file ?

Is the PDF named the same each time or are they creating a new PDF with a new name?

If it is a new PDF (name) each time then you can't do it.  Crystal only allows dynamic images.

If you just change the existing PDF then the report should update it on open or you may have to refresh the report.

Yes the PDF is named the same each time.
Are you suggesting to user .RefreshReport() method ?
This PDF is contained in a subreport, how do I refresh a subreport ?

The subreport should refresh when you refresh the main report.

SO long as the report is not saved with data, it should refresh on opening.
