3820722 - Why does my Expense Report hang/endlessly spin when trying to add or approve expenses with attendees?

When user tries to add or finalize an expense on an Expense Report, the session completely hangs resulting in an endless spinning/loading icon. This completely locks up the session and requires closing out the browser tab and re-entering the concur session to resume work. 
 

• When a spinning wheel occurs on expense types that have attendees, it is most likely due to either the Last Name or Attendee Name fields being set to Hidden
• The reason for this is because the Last Name field on the Expense Attendee form is by default set to be a Required field for the user, and therefore cannot be hidden
• The Attendee Name field on the Attendee Detail View form is designed to pull data from the Last Name, First Name, and Attendee Name fields, and should also not be set to Hidden

Only way to recover from this issue is to completely close out the browser tab and re-enter concur entity. , KBA , CON-CA-ADM , Administration , CON-CA , Cross Applications , Problem
