I have 8 years experience in SAP ABAP and BI with exposure to SAP BO. I am working on a HANA implemented system. But my knowledge is nil on HANA based modeling. Natural progression is to learn more of BO and HANA. However I'm more inclined to the function side of SAP. I know that its difficult to move to functional modules immediately. Hence I would like to know which would be the best way of progression keeping functional role in mind. I have decent knowledge in SD, PM and PP.
