Hello Pushpak,
As you are already working somewhere so why you are taking so much tension, just concentrate on your current domain, try to explore as more as you can, find the root logic, Follow the SAP SD space on SCN it will help you to improve your current knowledge. Once you feel like i am the expert in current domain, then you can start learning ABAP (because you' re interested in programming. ).. But don't put your legs in different different domain at beginner level.
