ABAP Development on SAP HANA

Optimizing custom ABAP development for SAP HANA

Based on a concrete example scenario (simplified Open Items Analysis)

Consider the following questions

How can I detect optimizing

potential on SAP HANA?

How can I optimize my existing

code with minimal investments?

How can I fully exploit the power

of SAP HANA?

What are guidelines and best

practices, and how do they differ

from existing recommendations?

Technology aspects of ABAP on SAP HANA

Key technology aspects of SAP HANA

Support for multi-core architecture ( benefit from massive parallelization)

Row and column based data store ( very fast aggregation and search)

High data compression ( make use of real-life / sparse fill of tables)

Key consequences for developing ABAP on SAP HANA

Database access becomes center of attention ( good DB / SQL knowledge is key)

Performance is not only an expert domain anymore ( tools and guidelines)

The consequence: A paradigm shift

Characteristics

Data processing code is running inside HANA

Less data transfer between HANA and ABAP

Reuse possible in non-ABAP scenarios
