Disable "Quit" and "Help" buttons in EWT based services

Dear experts,

We've several EWT based services and for all them the "Quit" and "Help" buttons are always displayed. We want to disable/remove these options.

We defined the following parameters for the EWT services in SICF
~TRANSACTION - XPTO
~THEME - 99
~WEBTRANSACTIONTYPE - EWT

We refer to the note 1010519 and it works fine for the webgui services but not for the EWT ones.

Could you please tell us if there is some parameter that can solve our issue?

And we don't want to edit the TEMPLATELIBRARYBASIS template...

Thanks in advace for any help.

Kind regards,

Sara
