How can I create an assignment if the person type I need isn't in the list?

If the missing person type is valid for the worker type, you must update the list of person types.

For example, if the worker type is employee and you want to use the person type trainee, you must update the list of employee person types.

If the missing person type isn't valid for the worker type, you must either create a new work relationship or update an existing work relationship of the relevant type. For example, to use the person type volunteer, you create the assignment in a nonworker work relationship if volunteers are classified as nonworkers.
