SUS-standard process to remove contact person

Hi All,

May i know how standard SAP SUS manage contact person?

Example: Supplier A have created a user by using "Delegated Administration" functionality in SUS portal. If the user had left the company, what will be the standard SAP process to remove the user from SUS system? Do we delete the Business Partner relationship manually? or there is a standard program to remove contact person?

Please advise.

Thanks,

William
