IDR AP Automation for multiple ledgers/BUs

Hi All,

When we send emails containing multiple invoices from multiple vendors across ledgers/BUs to workflow email, the system is creating all invoices under one BU. So, as a workaround we want to split the emails and so we created multiple email boxes but when we configure forwarding address in these mailboxes, Google is sending an email to Workflow email for us to verify the forwarding address which we are unable to do so.

How do others deal with configuring IDR for multiple BUs and making it work?

Thanks,

Asif Sk.
