Hi Venu,
To answer your questions:
RSECVAL doesnt hold anymore the details of analysis auth. This was move to another table as per SAP version. Check this thread:
BW Table RSECVAL doesn't show data
For the infoObject, yes you need to tick before it became authorization relevant and for you to maintain specific values.
I would suggest you check SAP Documentations about BW/BI Authorization.
Thanks,
Santi
