You can use a view to do this. If they need to modify the data, then you
will need to use rules to make an updateable view. The easy way to do
this is to have a table that maps users to the id_enterprise values that
they are allowed to access and for each table you want to grant access
to, join this special table in the view using the current_user as the
the user to test against.
