S_RS_AUTH versus S_RS_COMP, S_RS_ICUBE

Hi

I've a question regarding if I have a single role i BI that includes S_RS_AUTH with value "0BI_ALL" and some other objects in the same role like S_RS_COMP and S_RS_ICUBE are limited with some specific infoobject and reports.

Which effect comes out of this case??

From my view, this is like you have a "star" in the comp and icube object

Anyone who can tell??

Or, what do you use in which case??
