The reception scan is done from the Receptions menu. Select the receipt document from the list (supplier invoice or notice from another store).
Unlike shipping (where quantities are strictly limited to order), at receipt items can be scanned in different quantities than the original document — differences are recorded and reported automatically.
Items can also be added manually from the Information window → Show what's left to scan (requires ICS setting). Click on the item and follow the on-screen instructions.
