I have a custom record that houses information about a meeting (i.e. meeting type, attendees, date, time, secretary, etc.). I also have a Case(s) tab that is populated with a custom view of the support cases tied this meeting. What's the best approach for getting both datasets into a single Advanced PDF to produce an Agenda?

Create scripted template there you can pull all the datasets in one suitelet script.

Perfect! Thank you!
