How do I delete an invoice in Contract Management that didn't transfer successfully to Receivables?

Summary:

We have credit memos that errored out in Receivables when we transferred them from Contract Management. They errored out because we transferred credit memos for invoices that are already paid. So, we would like to delete the credit memos in Contract Management. We have already deleted the records from the AutoInvoice file in Receivables.

When selecting "Manage Invoices," the "Delete" and "Return to Draft Status" actions are grayed out for invoices that have been transferred to Receivables, even if the transfer resulted in an error.

How can we delete these credit memos in Contract Management?
