Pricebook Entry Match
If you are utilizing multiple Pricebooks in Salesforce that correspond to multiple Price Level's in NetSuite you should perform that match, and then perform Pricebook Entry Matching. That way when creating transaction records in NetSuite the correct corresponding items and prices are used. Navigating to Breadwinner for NetSuite -> Product Match -> Price Book Entries
You will be presented with a similar screen to Pricebook, Product or Company matching. Here you can match specific additional pricebook entries to individual item price details in NetSuite.
