I am IT professional and done ITIL, CISA certifications. Can you suggest which SAP course i should do?

Dear SAP Aspirants,

As i see your qualification and experience, I suggest you go for SAP HANA Modeling and SAP HANA Development. 

Since you are CISA certified, SAP GRC & Security module would be right choice for you. if you are not so much inclined towards security, you can learn any module of sap and play the auditor role.
