Maintenance on invoices
Your options for processing the invoice remain the same, regardless of the source that created the invoice.
Maintaining unreleased invoices
You can maintain an unreleased invoice in the Billing solution to update invoices, billing adjustments, and credit memos. You can also maintain a shipment-related invoice to change information such as price, comments, or freight charges.
If you invoice at more than one process level, then you can change the process level of an unreleased invoice to create a new invoice for a different process level.
Maintaining released invoices
Maintenance is limited on released invoices. You can add comments to the header or line.
Invoices that originate from the Item and Order Billing solution or from outside sources often enter the Billing solution as released invoices.
