⚙️ ABAP Managed Database Procedures (AMDP)
ABAP Managed Database Procedures (AMDP) is a powerful framework in SAP HANA that enables developers to create database procedures using the ABAP language. AMDP serves as an alternative to SQLScript, the traditional approach for creating database procedures in HANA.
With SAP HANA AMDP, ABAP developers can write database procedures using ABAP syntax, which provides the ability to use familiar ABAP constructs such as loops, conditions, and function modules. This makes it easier for ABAP developers to work with HANA database objects and enables them to leverage their existing ABAP skills.
🔧 AMDP Procedure Types
AMDP Methods
Used to perform database updates and modifications. These procedures can change data in the database and are defined within ABAP classes with special syntax and annotations.
AMDP Functions
Used to perform read-only operations. These functions retrieve data without modifying it and are also defined within ABAP classes using specific AMDP annotations.
✅ Advantages of AMDP
- ✓ Familiar ABAP syntax makes it easier for ABAP developers to work with HANA database objects
- ✓ Seamless integration with ABAP data types and structures
- ✓ Ability to leverage ABAP development tools such as code completion and debugging
- ✓ Can use existing ABAP function modules and classes within the database procedure
- ✓ Improved productivity for ABAP developers working with SAP HANA
🔚 Conclusion
ABAP Managed Database Procedures (AMDP) can be used in conjunction with other SAP HANA development technologies such as Core Data Services (CDS) and Business Objects (BOBJ) to create powerful, efficient, and high-performance applications in SAP HANA environment.
ABAP Managed Database Procedures
CDS Views Features
- ✓ Database independent
- ✓ Support Open SQL
- ✓ Advanced view building
- ✓ Returns single output
AMDP SAP Features
- ✓ Database dependent (HANA)
- ✓ Supports only HANA SQL
- ✓ Method in a class
- ✓ Can return multiple outputs
Architecture Note: CDS Views become database-agnostic HANA Views when deployed, while AMDP methods transform into native HANA Stored Procedures, explaining their different capabilities and use cases.
