Group Permissions
Each cell crosses a POS permission (cancellations, discounts, POS closing, printing…) with a user group. The groups are those assigned to POS users (Points of sale → POS access management).

Figure 9 — The permissions × groups matrix (Kiosk, Manager, Trainee, Cashier).
Each cell crosses a POS permission (cancellations, discounts, POS closing, printing…) with a user group. The groups are those assigned to POS users (Points of sale → POS access management).
Warning — each click is saved IMMEDIATELY (no Undo button). And a permission unchecked for every group becomes a "default right" inherited by users with no group.
