I'm using Crystal 8.5 to modify a PO report. The PO header contains a "VendorID" (integer). That POHeader.VendorID links to the Vendor table VendorID (integer). There is a field on the Vendor table called "VendorNum", and it's an integer field. This character field needs to link to a subreport that shows memos for that vendor. The field I need to link to in the subreport is a character field. How can this be accomplished?
