Where Can I Find the “Mark as Delivered” Option in a Purchase Invoice?
The “Mark as Delivered” option appears in the “Delivery” tab in the purchase invoice creation or editing form, after the section for entering invoice items. This option appears only when the “Requisitions for Sales Invoices” setting is disabled.
When you select the option, the “Delivery Date” field appears next to it, populated by default with the current date and time, and you can edit it.
