Profarma invoice - Proof of Delivery

Hi,

My client having POD scenario, in one case he made a profarma invoice of 15 days delivery and send to customer and take payment against it. but required that profarma invoice can only be generated only if POD is done, but in standard system i checked it, it can be done any time when ever we require, does not check that POD is done or not.

Have any possible alternate from my gurus.

Regards,
