Do not delete anything related to an invoice when a invoice is voided.

When voiding an invoice, notes, related documents, original approvals, etc. are deleted. These removed items are needed for future reference when referring to the voided invoice. I have also spoken to other firms who are also frustrated with the deletion/removal of all items/notes/docs/approvals/etc. related to the original invoice. We need for everything about an invoice to remain when it is voided and I am sure I am missing other items are about an original invoice that are removed when voided.
