Transactions at fueling points are initiated by authorizing the fueling point, then lifting the appropriate nozzle to dispense a volume of fuel, and finally replacing the nozzle.
When a transaction is created, it is not locked to any specific point of sale (POS) unless it is authorized with the preset or prepay option. In such cases, it automatically locks to the POS that authorized it.
In the "Forecourt Overview" panel, we see three transactions, two of which have already been added to the "Receipt" panel. Transactions included in the receipt are locked by the same POS ID that was used during login to the Demo POS. This means that locked transactions belong to us and cannot be locked by any other POS connection. This mechanism ensures that each transaction can be processed by only one POS connection.
To add existing transactions to the receipt, simply drag and drop them into the receipt list. Once a transaction is placed in the receipt, it is locked by your POS ID that you provided during login. If you wish to unlock a transaction, drag it from the receipt back to the "Forecourt Overview" panel. This action will remove the "locked by [your POS ID]" note, and the transaction will disappear from the receipt.
When the receipt is ready, pressing the "SALE OK" button on the Demo POS will clear all transactions in the receipt, and the relevant fueling points will switch to an idle state.
