Is SAP knowledge helpful for a mechanical engineer?

From my experience and observation, its a NO! Automobile engineering is a part of mechanical engineering but it's only a part. It's like suppose my area is games. So will it be mandatory for me to know cricket? The answer is only if I want to work with ICC or something aligned!

Knowledge is an asset which helps you one or other time. But to acquire knowledge depends on your interest. If you are interested to work with automobile giants then of course you should have sound know how of this subject. But then there are so many other areas like fm, tom, thermodynamics, designing & modelling software etc in mechanical engineering to work upon.

Of course you might face embarrassment when your father asks you the advantage of buying diesel car over petrol counterpart. But then use http://caredekho.com /cartreade.com or just google!!!!
