Allocated tickets to teams or Business Units (BU) can be auto-assign-ed to a user if a default assignee was selected upon setup of the Business Unit. However if there was no default assignee, allocated tickets need to be assigned to a user who will be inviting guests to the event.
TIP: The assignee will have "ownership" of those tickets.
They may invite the guest OR simply record the name
of the individual who used the ticket for reporting purposes.
On [Allocate to Business Units], locate your event and click [Assign].
Select a [User] and indicate the number of tickets out of the total open tickets, click [Assign] to assign the tickets to the user and close window.
Repeat step 2 for each of the users, until all tickets have been assigned.
Once all tickets have been assigned you'll see [None Left!] for each business unit allocated with tickets for the event.
Once all tickets are assigned to a user, the event is now released to Manage Guest List ready for adding guests.
