Billing-Posting date Control-User exit

Dear all,

Here the client requirement is the scheduled billing date should be automatically taken for posting date. If the client is giving posting date other than scheduled billing date system should show error message.

Is there any user exit for this or can any one write how to control this?

With regards,

Renju
