Sales Order Entry/Row security

Hi,
I set a row security for DCTO (Order type) in Sales Order Entry (P4210). They will be able to enter/edit/delete only one particular type of order (ST). Everything works fine (technically). However there is a small glitch there.
A user is able to run a version of the P4210, which allows him to enter another types of order (like SO). So the user can finish all the steps and there won't be an error message that the entry failed at the end.
Is there a way to prompt the user that he can't enter that order type or give him an error warning? The system is B7333 (XE).
Thank you.

Regards, Alex

There might be a processing option which allows protecting the order type,
so that if they have access to P4210, they can't change the document type.

There are several versions in the menu; the users don't have to change the order type as it is already there.
