How to check the authorization based on webdynpro application

Hi Experts,

I was asked to develop a webdynpro component with two webdynpro applications, one each for internal party and external party to be used.

So how to restrict or check the authorization based on webdynpro application used?

Do we have any authorization object like S_TCODE for webdynpro application in roles and authorizations?

Please enlighten me.

Regards,
