If cost centers are being used in the current company, the Agency / State File Maintenance screen will validate whether the operator has security authorization to enter a disallowed vendor code but disallowed vendors will appear in this screen if already assigned.

To determine whether the operator may add a vendor code, the software compares cost centers assigned to the vendor with cost centers in the operator's assigned cost center scheme, and if there are no matches, then that vendor code will not be allowed.
