SAP BI or SAP FICO

Hi,

I hold a Bachelors degree in computers and have a year experience in Software Developing(Used Data Warehousing). I also hold a MBA degree in Finance and currently working as a "Business Analyst" from past 6 months. Now I want to make a career in SAP, but confused whether I should go for SAP BI or SAP FICO. For a background as mine would you suggest SAP BI or SAP FICO as a successful career?Please suggest....and thanks for your suggestions in advance.

Thanks

Nikhil
