What is ABAP on HANA?
ABAP on HANA refers to developing and optimizing ABAP applications to leverage the SAP HANA in-memory database. It allows existing ABAP code to run on HANA while introducing new performance-optimized techniques like Code Pushdown, Core Data Services (CDS), and AMDP (ABAP Managed Database Procedures).
🎯 Goal: Shift heavy processing from the application layer to the database layer, utilizing HANA’s speed and parallelism.
🔷 Key Concepts
| Concept | Description |
|---|---|
| Code Pushdown | Executing logic at the database layer instead of the ABAP application layer |
| CDS Views | Enhanced SQL views built in ABAP layer with annotations and metadata |
| AMDP | ABAP-managed SQLScript procedures executed in the HANA DB |
| HANA-Optimized SQL | Use of new Open SQL syntax & inline declarations for performance |
| ALV with IDA | High-speed real-time ALV output via HANA |
🔷 Why ABAP on HANA?
- 🚀 Leverages HANA’s high-speed in-memory processing
- 📉 Reduces data transfer between app & DB layers
- 💡 Enables real-time analytics and reporting
- 🔄 Reuses existing ABAP skills with new performance techniques
- ✅ Supported by modern tools like Eclipse (ADT)
