Add P.Os from external system into Zahara

Add P.Os from external system into Zahara

We have a Workshop system where we create Purchase Orders (Due to having 1000s of Parts in the system) and it would be great if we could import P.Os with a P.O Number already assigned into Zahara, as the Invoice process could then continue matching in Zahara.

The import currently only supports the creation of new P.Os without a number.
