How custom ABAP code benefits from SAP HANA?
ABAP development guidelines
• Improved tools for performance analysis
• Extensions to ABAP and OpenSQL
• Features for SAP HANA-oriented programming
• Re-use components optimized for SAP HANA
Transparent optimizations
• Fast Data Access (new data exchange protocol)
• optimized SELECT... INTO ITAB and SELECT SINGLE
• optimized FOR ALL ENTRIES-clause
 The typical and recommended approach for customers who want to migrate their custom solutions to
SAP HANA (or have already done so) follows the pattern "Detect - Optimize - Explore".
– Detect your custom ABAP code to be adapted making use of the advanced quality assurance
tooling
– Optimize your custom ABAP code for SAP HANA by making use of the various programming
features
– Explore the new opportunities provided by SAP HANA and integrate them easily in your custom
ABAP applications
