Does mass update (native feature and not a custom script) trigger workflows?

Yes you can initiate, transition, or process workflows via mass update

depends on the mass update, a lot of the standard ones that arent general updates or custom updates dont actaully trigger scripts or workflows

@battk but the mass update process has functionality specifically just for triggering workflows. It’s not just updating a field and hoping workflows trigger

depends on if you think the point of the question is to use a mass update to trigger a workflow

I did not word my question clearly. What I meant was I have an existing workflow on POs. If I perform a mass update on those POs, will that workflow be triggered like its actions?

Oh I see. Then yes @battk is correct it is hit or Miss whether existing workflows get triggered

Ohhh that's noted. Thank you both.
