Steps to create Assistant:
1. Create a new assistant
a. Call nlapiCreateAssistant(title, hideHeader).
b. Add steps to the assistant. Use nlobjAssistant.addStep(name, label).
c. Define whether the steps must be completed sequentially or whether they can be
completed in random order. Use nlobjAssistant.setOrdered(ordered).
2. Build assistant pages
Add fields, field groups, and sublists to build assistant pages for each step.
3. Process assistant pages
In Suitelet, construct pages in response to a user’s navigation of the assistant. At a
minimum you will render a specific assistant step/page using a GET request. Then you
will process that page in the POST request, before then redirecting the user to another
step in the assistant.
