Current BBCRM functionality allows for the import of direct marketing effort files with test segments, but does not allow for variants in positions other than the test segment. In large, complex direct mail campaigns that contain thousands of source codes, and contain variants in multiple positions outside test segments, this requires setting up many (up to 35) direct marketing efforts per mailing. We need the ability to create a single direct marketing effort for a mailing, and have every source code import as long as it is unique. Our source code is 18 digits, and test segments can be no more than 10 digits. The ultimate goal is to be able to import source codes without using the test segment functionality, and that all unique source codes would import into the direct marketing effort with the only requirement being that the source code is unique. The system does allow this with manual data entry, but with thousands of source codes this is not possible to handle manually.
