Hi Obaid,
I don't know which ressources you have searched so far, but information on CA's training catalog is available at education.ca.com.
Search for "Business Service Insight" and you will be pointed to a list of available training sessions (both Web-Based or Instructor Led) :
http://education.ca.com/SearchResultPage.html?keywords=business+service+insight&stage=RunSearch&catalog=1&deflang=en
There are different sessions which make sense for Admin's, although none of them is named "Administrator Training".
If you don't find a selected course scheduled already you should reach to the team by using the "Contact Us for more Information" link or directly with your respective account team.
