I have an AR receipt entry with a cc charge that has been settled but the receipt entry will not post. The charge was applied to two invoices. Before the batch was posted, another entry was made to those two invoices with a credit note applied to them…

I already have the default setting that prevents an invoice from being entered twice, but is there a way to extend this to prevent duplicates across all companies in our system? Almost all of the bills that come to my office are addressed to 1 company…
