No see i figured that would be the way to go but for some reason it isn't merging the info, just creating new records for the info from the 2nd file. I must be doing something wrong. When uploading the 2nd file of data, i select to use the "PO Number" as the existing field for the PO Number field on the 2nd file and then leave the rest to create new fields. I thought it would then go look for that PO# in the existing records and add the new info to the corresponding record. Is it because there are multiple existing records with the same PO Number? Or am I just doing it totally wrong?
