Problems in Extraction of CRM data to BW

Hi Gurus,

I am new to BW and I have a doubt,is it possible to extract realtime data from CRM to BW after the next minute of the insertion of data in CRM If not what will be the time duration between the data entry in CRM and to extract that data to BW. Lets say endusers have created BP/Activity in CRM at 5pm and I need to pull deltas to BW at 5:02 pm as they want report on it at 5:15pm is it possible if not what will be the gap between the realtime data entry and extraction of that data to BW. Would anyone please explain me in detail. I appreciate it in advance.

Thanks a lot

Regards
