Crystal report – how to link fields

I have to make a report that links two fields after some string manipulation like mid({field1}, 3) = field2. Is there any way to do this? I have attempted a subreport, but that is a left outer join and doesn't limit the report results. I'm sure that can be done in the select expert, but the table will be huge before the selection criteria is applied (200mil records after Cartesian of the 2 tables).

I, not sure I totally understand you dilemma; however, have you considered linking both fields into a single variable something like, field_3 = Mid(field_1, 2, 3) & Mid(field_2, 3, 2) then sending field_3 to your report?
