Axapta 2009 Security

Hi,

i want give AOT edit permissions to some developers in Axapta 2009. But i cannot find how to restrict those developers from accessing particular tables. For example:

A developer who has AOT edit permission can not view or edit a table that he is not authorized to view in AOT. But when he just write a simple job which selects the table's data he can dot it without any restriction. How can i prevent him from doing this ?

thanks.
