In the Norwegian version of LS Central, a Customer-function tender (a tender whose Function on the Tender Type Card is set to Customer) cannot be combined with any other tender on the same receipt. A receipt that uses a customer-account tender must be settled exclusively against the customer account, producing a delivery receipt rather than a settled cash sale.
Behaviour at the POS
If the cashier presses a Customer-function tender key when a payment line is already on the receipt, the POS:
- Plays the standard error beep, and
- Displays the message "<Tender Type Description> cannot be used with other Tender Types".
The customer tender is rejected and no payment line is added. The cashier must either void the existing payment line and start the receipt over with the customer tender first, or finish the receipt with the existing payment and post the customer-account portion on a separate receipt.
Why the restriction exists
Allowing a customer-account payment to be partially settled with cash or card would generate a hybrid document that the Norwegian regulation does not recognise as either a valid Delivery Receipt or a valid Sales Receipt. The restriction enforces a clear separation between the two document types.
