Is there a way to add an internal email address for Seperate Remittance Advice Emails?

Summary:

We are updating an RTF template to hardcode CC email addresses, and the code we are putting in the header is not working as intended. The CC'd email is not receiving any emails. I am looking for a way to apply this update across all supplier site records in bulk, rather than modifying each one manually. We are testing in the Oracle Dev instance.

This is the code we are putting in the header:

<?format-date:/OutboundPaymentInstruction/PaymentInstructionInfo/InstructionCreationDate;’XDODEFDATE’?><?xdoxslt:set_variable($_XDOCTX, 'EMAIL_CC', ‘ap_remit_us@sarepta.com')?>
