3.6 Forms and fields

The forms below are described as you meet them: header first, then lines, then totals. Three habits apply to all of them. Money fields carry the document's currency code as you type, so an amount always says which currency it is in (1.11). Quantities always name their unit. And fields your company does not use — a dimension you do not track, a credit field while credit management is off — are simply not on the form.
