To clear the existing transactions, drag and drop them to the receipt list on the right side in the Demo Pos form. When put on receipt, they are locked. No other POS client can unlock or lock an already locked transaction. It is the way to prevent double billing for the same dispensing. For this to work user must ensure that each client connects with a different POS ID.
When a receipt is ready, pressing the SALE OK button on Demo POS clears the transactions in the receipt, and fueling points switch to Idle state.
It only a basic work procedure simulation. You are free to investigate yourself and try different scenarios.
