Guide me regarding FI/CO Certification Trainings

Dear Gurus,

I am a B.E. Electronics, and working in ABAP for last 1.5 years,

I want to go for SAP FI or SAP CO certification training.

Currently i do not have any finance background, but i am willing to do a MBA in Finance after 3-4 years down the line.

Could any one please guide about, which certification training?(SAP FI or SAP CO) should i go, which will suit me and help me in my future studies as i will be doing MBA in Finance.

Thanks,

Bhupender
