See everything that happened to an order
Who sent it, what changed, what the supplier said, and when.
What this is for
“Who changed this and when?” used to have no answer. Every purchase order now keeps a history — raised, sent, amended, received, checked, cancelled — including the supplier's own answers from their link.

What is on this screen
Each part of the screen above, top to bottom, and what changing it affects.

Tips & gotchas
- The history is never edited or deleted, only added to. That is the point of it.
- It records emails that failed as well as ones that sent — “could not email orders@supplier.com.au” is the useful line, not silence.
