In most cases when you do business with a master agent you get your commission data on 1 spreadsheet which includes commission items for more than 1 supplier you are getting paid for. Ideally you want to split up the commissions for each supplier allowing you to see exactly how much commission your received for each supplier. Before we developed the multi supplier import you had to split up the spreadsheet into individual spreadsheets to get this accomplished. 

This is no longer necessary!

The multi supplier import feature allows you to import one spreadsheet and RPM will import the commission data to the corresponding suppliers you have setup in your subscription.
