This is where you enter the date of the accounting voucher. This is the date when the invoice should be recorded in the accounting. This is usually the same as the invoice date, but you can always select another date if needed.
You can configure the system to automatically set the voucher date as the same as the invoice date. This is determined by the setting Suggest Same Voucher Date as Invoice Date?, under the section Accounts Payable under the Purchase tab in the Settings procedure.
You can change the voucher date on an already registered invoice provided that it has been preliminary registered/preliminary coded. In order to change the voucher date on a final coded invoice, the ledger must not have been transferred to the accounting. If the ledger has been transferred to the accounting, this field is greyed out (cannot be changed).
