SALES HEADER FORM FIELDS NON EDITABLE

Yes, you can. But the question is why?

You can do it on the onaftergetrecord trigger and do something like:
IF "your condition"=TRUE then BEGIN
CURRFORM."Sell-to Customer No.".EDITABLE(FALSE);
<all other fields>
..
..
END ELSE BEGIN
CURRFORM."Sell-to Customer No.".EDITABLE(TRUE);
<all other fields>
..
..
END;

But why are you doing this? Are there certain users that cannot change a Sales Order?
Then it might be easier to revoke their right to change the table through the security settings.

Also if it is only a certain group of people then I would revoke them access to the regular Sales Header Form.
I would create a copy of the Sales Header form and then set all the fields to non editable and make that new form available to the restricted users.
Doing it through code is just a lot of coding, since there are quite a few fields on the Sales Header.

Hope this helps,

Regards,

Willy

IS THERE ANY POSSIBILITY TO DO THIS THROUGH CODES.

Don't use capital letters while posting. It amounts to shouting....

Take a look at 2-Controlware's Field Security module. With this module you can secure fields and sets of records. Ask your partner about it or use Google.
