The form

The rules that apply here
Everything on this screen obeys the platform rules rather than rules of its own. The ones worth knowing before you use it:
- Narrowing a list — search, conditions, sort, totals, export and saved views.
- What may be changed — the five grounds a record may not be edited on.
- Companies and business units — what the switcher above this list is doing to it.
- Creating a record — required fields, where choices come from, and how the number is allocated.
- Importing a spreadsheet — this screen accepts one, and it runs through the same rules as typing.
