You can enter receivables, i.e. a payment that was not immediately performed by your customer, but only once the period indicated on the receivable has elapsed. A receivable journal must be created per bank.
You can also enter Payables, i.e. amounts that the company must pay at a given date.
Creating a payable journal per bank is not mandatory.
These screens can be accessed from the menu bar Cash position > Payables or Cash position > Receivables.
