Need suggestion for learning SAP BO

Hi All ,

Need a suggestion related to learning SAP BO .

I have worked in a project on SAP BO using WEBi for 8-9 months. But I worked mainly on tool only or I can say for functional part.

Now I want to build my career in this technology only so it will required a detail knowledge of the tool along with Universe and all major , minor things.

My question is that should I go with the training of SAP BO only ?

Or first I should learn SAP BW then BO ?
Or SAP BO and after that SAP BW ?
