Delete User

Deleting a user is described in the above diagram. The administrator passes the user ID to the system.

The system checks to see if the corresponding user possesses any customers by checking the Customer datastore before flagging the user as inactive (deleted).

The returned status corresponds to the success of the operation. If the user is successfully flagged as deleted in the user datastore, the status returns Successful. If the user still possesses any customers, the administrator is notified of this condition and must transfer the customers to another salesperson.
