Which guidelines should be followed to optimize ABAP code running on HANA?

Focusing on column store utilization is a key guideline for optimizing ABAP code running on HANA. Since SAP HANA is designed with a columnar data storage approach, leveraging this feature is essential for achieving high performance in data processing and querying. Columnar storage allows for better compression and faster data access patterns, which directly improve the efficiency of ABAP programs that are accessing data stored in HANA.

When you optimize your ABAP code to utilize column store effectively, you can take advantage of HANA's in-memory capabilities, resulting in quicker read operations and improved overall application performance. This optimization approach often includes using appropriate SQL constructs to ensure that the data access patterns align well with how data is stored in the columnar format, thus making the best use of HANA's strengths.

Other options, while they might seem beneficial, do not represent the primary focus in the context of optimization specifically for HANA's architecture. For example, implementing Open SQL settings is useful but not specifically targeting HANA's optimization, and adjusting technical settings can assist with performance but is more of a general configuration task. Using deprecated database properties, on the other hand, would be counterproductive as these properties may not be supported in HANA and could hinder performance or lead to instability
