Hi Seema,
You need not to be confused or panicked. Basically there are two types of jobs associated with SAP in any organisation. One is implementation part and the other one is support function. Implementation means you have to develop the program for the organisation whereas support means it is already implemented and u have to just work on it. Implementation is a vast job and basically companies look for experienced people. As already been told Siemens is the certified trainer for same but it is very expensive(approx. Rs 3 L). Now it depends upon u how much do u want to spend. Siemens train you first and then let you work on implementation-projects under their guidance so that u get implementation experience. Apart from that u can do a one year course fron C-DAC (Noida). Though it's not certified as the certification lies only with Siemens. its a govt. institute and the course fee is also approx Rs 60,000/- which make it a good bargain as it also gives u live-experiences. Many companies take people from this institute becoz the faculties are themselves top honchos of SAP companies. It's over all a good deal.
Apart from this there are many pvt institutes offering SAP course at a cost of Rs 25000/- to 30,000/- These institutes are good for working people as they are having flexi-timings & if u are having good domain experience then it helps u a lot. I am a HR professional with a exp. of 3.5 yrs and since I can't afford to leave my job I am doing the course from such an institute in the evening hours & on Sundays. For Siemens or C-DAC, U need to devote full time.
SAP is very much in demand. Be it implementation or support function. You can go for the same without hesitation. It will help u in future.
Hope U got ur queries solved. U can ask me if u are having any more.

Amit Singh
