3824402 - How do I add a Non-profiled employee as an Attendee on an Expense Report?

I would like to add our IT personnel as an attendee but I don't know how. He works with our company but he doesn't need to create any expense report that's why we did not create him a profile in Concur.

Client would like to add an employee as an attendee but this person doesn't have a Concur profile. , KBA , CON-EXP-ADM-ATN , Attendees , Problem
