One way to do this would be to add a second copy of the table that contains the transcodes. When you do this, Crystal will throw a warning that the table is already in the report and ask if you want to "alias" the table. It will then add the table with "_1" on the end of the table name. We are going to use this second copy of the table only for filtering data - it will NOT be used anywhere on the report itself. If the original table is called "MyTable", the aliased one will the "MyTable_1".
1. Create an inner join from MyTable to MyTable_1 using whatever field(s) identifies your data. DO NOT use the transcode field for this!
2. In the Select Expert, add something like the following:
MyTable.TransCode = 'CRV' and
MyTable_1.TransCode = 'BGE'
Also add any other filters that you need for your report, working from MyTable and NOT MyTable_1.
This should get you the data you're looking for.
