You can interface, change, and re-interface invoices as often as necessary; however, you can only interface billings with an assigned invoice number.

The GL Close form does not allow a month to close if there are any invoices that require interfacing for the month. Additionally, you can also change and re-interface billings that are in a closed month. However, closed month billings must re-interface to a month that is open in both JC and AR. Because the batch selection form automatically defaults the closed month, make sure to change the batch month to an open month before interfacing.

For more information about the interface process, see Interface Billing Invoices.
