De-Activation of Installment plan at final bill during Invoicing

Hi,

In de-regulated scenario During Invoicing if there is a contract move out or contract account move out, what configuration we need to do to deactivate the Installment plan linked to the customer.

It may be similar to deactivation of IP during final invoice.

We would like to deactivate IP through config rather than writing some custom code in the events.

Please suggest.

Regards,

Suresh
