Revisit this issue.

The client contacted me & sent me an email. Here is exactly what he wrote me:

I seriously want to voice a concern request for Adagio to change the software to allow certain changes.
It is a PAIN IN THE REAR when we make a mistake on a PO #, not for us to be able to change and resend the invoice.
It is a huge disappointment to me and I want to know how to get it changed.

This issue is in OE. They sent the Invoice to their Customer with an incorrect PO. The Customer refuses to pay until they modify the Reference/PO # and resend the Invoice.

In order to do this, the only way I can think of making this happen is to Credit the Invoice & reissue the Order & create another Invoice, all with the same date.

Notwithstanding that this is an indexed field, can you not still allow for editing the field (and of course, maintaining the index)?

I know that this may take some doing, but in my mind, the client is asking for something that sounds reasonable and unfortunately happens. This would be a nice enhancement.
