Question - I wish to post from an external system to a NetSuite RESTlet. I'll be passing in a JSON array of objects. Each object contains a customer ID (NS internal ID) and a couple other fields for comparison. In Netsuite, I want to find all the customers, update 1 field in NS, and compare the second field. I need to return a new JSON array with a list of any customers where the second field is different between the 2 systems, so the external system can update itself. What's the most efficient way to do this? Map/reduce feels right, but I could also do a serial iteration.
