what is the qualification required for joining the sap??????????

it's my understand that a practical environment is essentials. Additionally, for BASIS, you need sufficient OS/DB background; for FI/CO, you need sufficient financial background; and so on.

Hi Belala,
First you need to have experience in other ERPs before entering into SAP. Or you should have worked functionally (in a/c dept, Purchase and sales depts etc,,)

knowledge on computers means from basic onwards and u must have a degree

There are many ways to learn about SAP: book, online training, class and self-study CBT materials. I guess the challeng is how to find the most fitting materials. SAP has a great future.
