I would like to share my SAP HANA certification exam experience and some of the TIPS for the preparation of SAP-HANA certification.

First I would like to brief about myself  , well, I started my carrier as programmer and then got interest in database development.I am NON-SAP professional,having hand on experience in MSSQL,MSSAS. I then started reading about In-Memory database technology and quite impressed with SAP-HANA technology and platform as In-memory database which is dual in nature (OLTP as well as OLAP).I generated huge interest to learn the new innovation technology HANA. I started my learning journey of SAP HANA in the starting of year 2014 and today on 22nd May 2014 I became SAP CERTIFIED APPLICATION ASSOCIATE-SAP HANA by qualifying the certification exam and scored 97%.

My MSSQL knowledge help me a lot to understand the SQLScript,Procedure,database development part of SAP HANA.

My MSSSAS knowledge help me to understand the DATA MODELING concept of SAP HANA.

My MSSIS knowledge help me to understand the ETL technology of SAP(BO-DATA SERVICES) of SAP HANA.

      Hi,

      To appear for SAP HANA certification ,experience is not mandatory if you are appearing for exam from SAP global center,BUT if you are appearing from India then I believe experience on HANA is prerequisite.

                    Experience required

               ELSE take training from SAP

                    No Experience required.

            Hi,

            Thanks for Reply my question, Please clear one more thing-

            I have Exp. on SAP ABAP but No Exp. on SAP  HANA(I am prepared for certification by self study only).

            so SAP HANA exp. is  required for SAP HANA certification?

            or SAP ABAP Exp. sufficient for certification .

            Thanks.

              Hi,

              If my understanding goes wright ,SAP HANA experience will be required.You may validate this with your nearby SAP center because they are the one who validate your prerequisite doc and issue you exam voucher to register with VUE.

              Rgds,
