How to select SAP module please help

Hi guys,

I am an IT engineer passed out in the year 2010. After completion of engineering I certified myself with Oracle database administration from Oracle corporation, but instead working with software firm, I am working as a project coordinator in construction company for past 2 years. Now I again want to start my career in SAP either technical or functional module. Please I request you all to help me and guide me the correct path. Guess you guys are experts in such courses and believe that some one might show me the correct path for my future.
