You can match data in an input file with source records and then import selected records or all records. You can preview and analyze the match results before you import records. Customer 360 SaaS doesn't store the input file data until you import it.
For example, an automobile manufacturing company wants to procure auto ancillary parts. The company shortlists vendors and uploads a CSV file that contains the shortlisted vendor records. The company wants to match records in the CSV file with all the source records in Customer 360 SaaS and import selected records. After the match process completes, the preview results show records that match and those that don't match. The company selects the records that don't match to import the new vendors.
