HI,

I am working as a SAP Security and GRC Consultant from last 20 months, but  i always have some doubt/concerns about the career growth and future in this SAP Module.Also i am having some interest in other modules too specially functional like MM.

Please advice me what should i do know, or what is the future growth in SAP Security and GRC.

Thanks!!
