Noob question here...I need to use an advanced PDF template to print off results from a saved search. However the search I am trying to print cannot be built with a single search, I need a developer to create a script which creates a page combining the results of the searches. Can I print an advanced PDF from that developer-created search results screen?

Would need to be a Suitelet script to run the searches, compile the results, and render the PDF.

Yes you can script the searches and combine them into a single JSON object and use the JSON object as your datasource.

Thanks @suitedev. So it would not be an advanced PDF template that generated the PDF, it would be the script?

You can use an Advanced PDF Template to render the PDF, but as Eric said, you would first need to create the JSON Object and provide it as a data source.. That is the most direct path.

Thanks to you both!

Yes just think of it as a mail merge. You have a template and you have the data that will be merged with the template substituting the data with the placeholders on the template.
