To do or not to do?

Hi,
I?m in a bit of a dilemma.
I graduated two years ago in I.T, but never knew what to do next. I?ve been floating around with my career starting with support and at present I am working as a software tester. I?m going to attend a course in SAP BW, which is costing me an arm and a leg.

I have been searching job sites for SAP BW Job, but all the jobs I?m seeing requires 2 years experience.
I?m I going to find it difficult to find a job once I become certified? Is it worth doing this course?

Please advise
