Best Understanding CDS Views and AMDP in Modern ABAP Development 2025

The SAP ecosystem has evolved dramatically over the years, with modern ABAP development now focusing on performance, scalability, and database-centric approaches. Two key technologies enabling this evolution are Core Data Services (CDS) Views and ABAP Managed Database Procedures (AMDP). These tools empower developers to push complex logic closer to the database layer, optimize performance, and deliver rich, data-driven applications.

In this article, we will explore Understanding CDS Views and AMDP in Modern ABAP Development, their features, benefits, use cases, and best practices, helping ABAP developers understand how to leverage them in modern SAP projects.

What Are CDS Views?

Core Data Services (CDS) Views are an advanced way of defining database views in SAP. Unlike traditional SQL views, CDS Views allow developers to build semantic data models directly at the database layer, following the code-to-data paradigm. This approach moves data-intensive operations closer to the database rather than executing them on the application server, leading to significant performance improvements.

Key features of CDS Views include:

• Simplified Data Modeling: CDS provides a clear, declarative syntax that is easier to read and maintain than conventional SQL statements.

• Annotations for Metadata: Developers can add annotations to define UI behavior, security authorizations, and analytics integration.

• Integration with OData Services: CDS Views can be exposed easily as OData services, enabling seamless integration with SAP Fiori applications.

• Reusable Models: CDS Views can be consumed by multiple applications, reports, and analytical tools, ensuring consistency across the enterprise.

For example, a CDS View can combine multiple tables like sales orders, customers, and products, and provide a ready-to-use dataset for Fiori apps, analytics dashboards, or custom reports.

Benefits of CDS Views

The adoption of CDS Views in modern ABAP development brings several advantages:

1. Performance Improvement: By executing logic at the database level, CDS Views reduce the volume of data transferred to the application server, speeding up queries and reports.

2. Reduced ABAP Code Complexity: Since data modeling and logic can be pushed into the CDS layer, ABAP programs require less coding, making them easier to maintain.

3. Seamless Integration: CDS Views work well with transactional applications, analytical tools, and SAP Fiori/UI5 apps, enabling end-to-end solutions.

4. Security and Authorization Management: Annotations allow developers to define access restrictions directly in the CDS View, ensuring secure and compliant applications.

In essence, CDS Views are the foundation for modern, data-driven SAP applications, particularly when combined with SAP HANA’s in-memory database capabilities.

What Is AMDP?

ABAP Managed Database Procedures (AMDP) is another powerful tool in modern ABAP development. Unlike CDS Views, which are primarily for data modeling and reporting, AMDP is used for writing complex database procedures in SQLScript (specific to SAP HANA) within ABAP classes. This allows developers to execute data-intensive operations efficiently without leaving the ABAP environment.

Key features of AMDP include:

• Embedded in ABAP Classes: AMDP procedures are created within ABAP classes, marked with the AMDP annotation, enabling easy management within the ABAP repository.

• Direct Database Execution: Procedures run directly on the database, taking advantage of HANA’s in-memory processing and parallel execution features.

• Complex Logic Support: AMDP allows loops, conditional statements, aggregations, and other advanced logic to be processed efficiently at the database layer.

• Version Control and Transport Management: Since AMDP code resides in the ABAP repository, it benefits from SAP’s standard transport and version control processes.

AMDP is particularly useful for scenarios like mass data processing, complex calculations, or tasks that require highly optimized HANA-specific features.

Benefits of AMDP

Using AMDP in ABAP development offers several strategic advantages:

1. High Performance: Data processing occurs at the database layer, minimizing network traffic and reducing execution time.

2. HANA-Specific Optimization: Developers can leverage HANA’s advanced features, such as parallel processing, window functions, and calculation views.

3. Centralized Management: All procedures remain within ABAP classes, simplifying version control, transport, and maintenance.

4. Complex Data Operations: AMDP allows handling tasks that would be cumbersome or inefficient with standard ABAP loops and internal tables.

With these benefits, AMDP has become a standard tool for developers seeking optimized, high-performance solutions in SAP HANA environments.

When to Use CDS Views vs AMDP

Understanding the right use case for each technology is key to modern ABAP development:

Use CDS Views when:

• You need reusable, semantic data models.

• You are integrating with SAP Fiori/UI5 apps.

• You want annotations for security, UI, and analytics.

• The logic is primarily about data retrieval and aggregation, rather than complex calculations.

Use AMDP when:

• You require complex business logic or heavy data processing.

• You need to access advanced HANA-specific features for optimization.

• The process involves loops, conditions, and transformations that are best executed at the database level.

In practice, CDS Views and AMDP are complementary. CDS Views handle data modeling, reporting, and integration, while AMDP executes performance-intensive operations, ensuring that the ABAP system leverages SAP HANA’s full capabilities.

Best Practices for CDS Views and AMDP

1. Push Logic to the Database: Minimize processing on the application server by using CDS and AMDP for calculations and aggregations.

2. Use Annotations Wisely: Include only necessary metadata and security annotations to keep CDS Views efficient.

3. Modular Design: Break complex procedures into reusable CDS Views or AMDP methods for easier maintenance.

4. Performance Monitoring: Regularly check execution plans and optimize queries in HANA Studio or SAP Fiori analytics.

5. Version Control: Maintain all CDS and AMDP objects in the ABAP repository to track changes and ensure smooth transport management.

By following these practices, developers can deliver robust, scalable, and high-performing ABAP applications.
