@girieshg It's a user event script, loaded using record.load() and saved via rec.save(). I'm on the phone with support and it's looking like this is not supported, however there might be a way to trigger the transition programmatically with one of the workflow module methods.

just to clarify, you have a UE running on some record that loads and saves some other record, and that other record has an active workflow that should transition after record.save(). NetSuite support says this is unsupported. Have I understood correctly?

Yeah that's right. I'm testing it right now but it looks like

workflow.trigger(options)

can trigger the transition from the script.
