To print the invoices, the checks (transferred checks) have to be selected first. A bill is marked, when a Tick is displayed in the first column. A left mouse click into the first column or the spacebar will (un-)mark the bill.
Now click on the printer icon to print an invoice for the marked checks. For each ( main-) ledger account an invoice with a separate invoice number is created, with all the selected bills on it. According to the layout of the invoice, the selected bills will be displayed detailed (per article) or as one amount per bill.
Bills, which are already invoiced, cannot be opened by the Amadeus - PM PRO | POS+ terminal again.
