Has anyone successfully rendered multi-language translations based on customer language preference?

Yes! We have just completed a two month long process to do exactly this, to provide alternate translations in German for all of our templates, based on customer language preference. Some of the field labels on standard records provide translations out of the box, while for custom fields and records you need to create your own using a translation collection (or by setting language specific labels on the fields or forms). I’m happy to help with more specifics. The SuiteAnswers are not terribly helpful on this subject, so it took us a lot longer to figure out than it should have. The SA article is here, but fair warning that there are typos in all of the code samples, so they do not work: https://netsuite.custhelp.com/app/answers/detail/a_id/87471 I can help with functional syntax, if this is the approach you want to use.

@scottvonduhn Awesome! I will contact you if I run into any snags. I kept looking for that help article, and couldn’t find it, and then I looked in the SuiteBuilder Advanced PDF Templates Reference, and it’s not mentioned there either.

The correct syntax to use actually looks like this:

@scottvonduhn Thanks again! I am digging into it this week and will let you know how it goes!
