The Vendor Invoice Person selection criteria can be used to indicate which types of users should be included in the output.  With this control, you can specify whether the resulting output should not include any Vendor Invoice Persons, include Vendor Invoice Persons along with other users, or include only those users designated as Vendor Invoice Persons.

The Vendor Invoice Person designation is set on the Person Profile >> Roles tab.

Using this control, you can additionally specify whether the resulting output should have an additional column noting which users have this Vendor Invoice Persons designation.

This option will only appear if your installation is running with the Project Financials family of Unanet licenses.
