Prior to launching Detect, we already had an audit process in place, so a report being returned wasn't necessarily new to our users. That said, the new status of "Pending External Validation" in Concur was new, as was the fact thateveryreport was now being audited. We also knew it was likely that the number of reports being returned would increase.

We didn't send out a separate communication, but did include a mention in our monthly newsletter ahead of launch giving a heads up and very basic details. We still got some questions from users, but I think it reduced that volume.

We also found it helpful to set up several Reject Template Messages in AppZen that the auditors can select when returning reports. It makes sure that the reason is explained well (I don't always think that the AppZen messaging is all that clear), and that messaging is consistent.

Best of luck!
