Hi Shreepad,
Please refer to the following thread in which the '/olap' view has already been discussed in details.
http://scn.sap.com/thread/3269108
Just out of curiosity, why do you wish to access the '/olap' views from _SYS_BIC schema. And if at all you need to access the views to get the data, then you can access the Analytic view from the package directly.
Can you please elaborate more on the requirement.
Regards,
Ravi
