sir what persentage required in 10th ,12th & b.tech to get job in SAP(ERP).

no not necessary, you have to its course, but remember entry in erp fields are not easy and positions are also limited, do some job market research before entering.

if u pass is enough and the grading is also there based on the percentage also if u want to do sap in big one u need a min 60%

minimum pass would be enough for it. if u r getting into private educators
