S_START and Webdynpro application for Access request, Model user, etc.

Hi All,

For PFCG role, do we need to maintain auth. object S_START, and if so how. In SU24, for S_START, i could not find any Webdynpro/TADIR(R3TR WDYA).

Also, ho do i find the Webdynpro application for Access request/Model user/Copy request, i.e in Menu tab, i do not get a search option to find teh Webdynpro.

Regards

Plaban
