🚀 CDS vs AMDP in ABAP on HANA: When to Use What?

In the era of ABAP on HANA, the ability to push data processing to the database layer is key to unlocking high performance. Two powerful tools make this possible: Core Data Services (CDS) and ABAP Managed Database Procedures (AMDP). But how do you choose between them? 🤔

Here’s a quick guide:

CDS (Core Data Services)

✅ Best for: Data modeling, aggregations, and declarative queries.

✅ Highlights:

• Database-independent syntax.
• Ideal for building views and exposing data to SAP Fiori or OData.
• Rich annotations for analytics and UI integration.

Example Use Case: Simplifying complex joins and exposing data models for analytical apps.

AMDP (ABAP Managed Database Procedures)

✅ Best for: Procedural logic and complex database operations.

✅ Highlights:

• HANA-specific SQLScript for maximum control.
• Perfect for loops, conditions, or advanced HANA features like temporary tables.
• Optimized for high-performance scenarios.

Example Use Case: Handling large-scale data processing that involves iterative logic.

How to Decide?

• Use CDS when you need simple to medium-complexity data models, or want to expose data for consumption (e.g., Fiori apps).
• Use AMDP for heavy-duty, procedural logic where CDS or Open SQL isn’t enough.
• Often, the best solution combines both: CDS for data preparation and AMDP for advanced logic.

CDS + AMDP

In many cases, you can combine CDS and AMDP for maximum efficiency:

• CDS for data preparation (joins, filters, aggregations).
• AMDP for advanced processing that requires procedural logic.

💡 Pro Tip: Let HANA do the heavy lifting—keep logic close to the database for optimal performance!
