Cancelled status codes for Receivable invoices

Cancelled status codes for Receivable invoices

Content

I am looking at an invoice consolidation process for a client. 

During this process, some source invoices will be replaced with a consolidated invoice.

The Client wants to cancel or put another code on the old source invoices so that they will not be available in reporting.

We are also looking at auto invoice grouping rules as an option. 

Couple of questions around cancelling a Receivables invoice:

1. Are there any other status codes for an invoice to not display on reports and aging inquiries besides Cancelled?

2. Can a Receivables invoice be cancelled if it is in draft accounted or final accounted status?
