Skipping and entry in a batch input session

I've created a BDC program to upload our vendor master records. I've coded the program to write all of the errors to a batch session to be processed later. When processing the batch session I realized that one of the first vendors is a duplicate (which is why it was erroring) so I need to skip that record and move on to the next one (without ever processing the duplicate.) Is it possible to do this? How can I get past this record and continue processing the rest?

Thanks!
