When I create one I can select a customer of course, journal, date, and memo.
Under that is Sales information which has Account/Description/Amount/Analytic Account.
What do I need that sales information for? and how does it work, when I click on the dropdown box under Account it shows no information and the only accounts in that specific customer is Account Receivable and Account Payable which do not appear in that dropdown box.
EDIT: I checked the DB table Account.Voucher looking to find any info on the specific field for account but there was nothing to be found.
The first account of Internal Type "Receivable" and Account Type "Account Receivable" will show up in the dropdown box. If nothing is showing up, perhaps your accounts are not setup correctly?
