Is there a way to have a rejection process for SO? It seems that SO is not part of the approval routing preferences which is probably why I can't have a Rejected status option unlike in other transactions?

Set it to Cancelled?

Cancelled can't be reopened though, right?

closed, can be reopened.

You would need to use an SO Approval Workflow to incorporate a rejection option.

Yes, but I can't control the status though at the top where it should say "Rejected" @Tigran I'll check if closing the SO is fine. @leo_ns Thank you.
