for which module of SAP scopes more in india and bring high earnings?

Answer 1

Most of the SAP consultants know one or more modules.

A SAP basis consultant is very easy to find so he will not cost much. A SAP consultant with FI or MM or PP or SD or HR is also rather common so his salary is not high especially when he has no expererience. When a consultant knows a less common module and has some experience then his salary will be much higher. Especially if no training is available in India. Think about Industry solutions.
