Process of printing invoices and credit memos
When you print invoices and credit memos, the invoice process in the Billing application is finalized. You can no longer maintain the invoices and credit memos in the Billing application after printing.
You can only print invoices and credit memos in a released status in the Billing application. You must release invoices or credit memos in an unreleased status before printing. Before you can print invoices and credit memos, you are required to run Invoice Print Edit Report (BL121). If you select the Run Invoice Edit option at the company or process level, then viewing invoices and credit memos one last time before printing is a required step in invoice processing.
