A container line prints a generic code ("MPLANT05") that the plant register
does not carry, so it had no asset to book to and sat unbooked forever. Each
site now records the container it hires — the code the invoice uses and the
plant item it books to — and a line arriving on an invoice for that site is
allocated to it automatically on import.
The lookup is scoped to the invoice's OWN site, not globally: two sites can
each hire an "MPLANT05" unit, and each line must land on the unit actually at
its own site. Covered by unit tests rather than by deleting a live invoice
and re-importing it.
A code with no asset is refused on save — it would auto-allocate to nothing —
and both or neither is required.
Assigned and booked: Autumns Gate "MPLANT05" -> SC02, The Hills "MPLANT05" ->
SC03, and The Hills' stuck line is now booked and earning. Container lines on
future invoices for those two sites will be booked without anyone touching them.
