AP invoice baseline date determination

We have configured 6-7 different payment terms for our vendors with varying bases for baseline date determination (document date, posting date or system date). Some invoice entry users change baseline dates at times which the management doesn't like and have asked if baseline date can be made read only for all users so that it is derived by payment terms from vendor master and users are unable to change it.

I just wanted to have your views if I can make this payment terms derived baseline date read-only for the users.

Thanks.
