Updating Segments in LiveRamp

If your customer updates the data for an existing segment, a new file with the updated data should be uploaded to our SFTP. The column heading in Column O in the new file must exactly match the column heading in Column O in the original file so that the identifiers correctly fall under the right segment. If the column heading in Column O is different from the original file, the new file will create a new segment.
