@Joe L. I do have customers using our iPaaS platform
integrator.io for integrating ADP and NetSuite. I just followed up w/ one of our customers on the exact q you posted and how they manage this...I learned you have 2 options here: #1 To map ADP preferred name to a NetSuite custom field and legal name to First Name/Last Name field. You can then have workflows in NetSuite as appropriate to drive business logic #2 Map ADP preferred name (if present) directly to the First Name field in NetSuite.
