Every Tom, *** and Harry is after SAP training now a days without checking the job prospects or market intake.
I am an SAP certified candidate with a wealth of ERP experience, but honestly I could not find a job in SAP for the last 1 year.

My advise to all " Never go for authorized centres and spend huge money ..No one asks for certification, only asks for SAP experience. So if you can find an institute or company which gives on job training, then go for that only." I have gone for many walkins with my certification, but could attend a single interview till date as everybody asks for experience ( how to gain first experience is a big question!!). So before spending huge money ask the SAP authorized institutes for references (contact nos) from students who passed out in the last one year or six months and talk to them.
If you want to move to an ERP, go for Microsoft great plains or axapta or Oracle EBS, which offers better opportunities.

Recently a friend mine got placed for Rs 150000/annum in hydrabad after shelling out Rs350000 for one month course. Funny thing is the institute notice board shows his monthly salary as 400000/annum :).
