Please help me in selecting the right SAP Module

Hi All,

I hope someone could help me out in selecting an appropriate in SAP for me.

I have done my MBA(General Management) and have 3 yrs experience in Project management. But currently I am planning to change my career to SAP and so I have done my research in the SAP modules, I could see that BI, FICO, MM, SD, BPC, ABAP, BASIC as the best modules for the long term career.

SO could anyone suggest me which module is best for the career and have good job opportunities in the market to settle down.

Please help me to select the module.

Thank you
