21. How do you enable and use SQL performance trace in ABAP on HANA?
Answer: To enable SQL performance trace in ABAP on HANA, you can use transaction ST05. It allows you to trace and analyze the SQL statements executed during program execution for performance optimization.
22. What is the purpose of the ABAP Managed Database Procedures (AMDP) framework?
Answer: The AMDP framework in ABAP on HANA provides a standardized approach for executing database procedures directly in the SAP HANA database, allowing for improved performance and flexibility in data processing.
23. How do you pass input and output parameters to AMDP methods?
Answer: Input and output parameters can be defined in AMDP methods using ABAP annotations, and they can be accessed and modified within the AMDP methods using the corresponding data types.
24. What is the difference between a CDS view and a database view in ABAP on HANA?
Answer: CDS views in ABAP on HANA are defined using ABAP annotations and provide a semantic data model, while database views are created using SQL and are primarily used for data access and reporting purposes.
25. How can you monitor the performance of ABAP on HANA applications?
Answer: Performance monitoring in ABAP on HANA can be done using tools like the SQL Performance Trace (ST05), SQL Monitor (SM50/SM51), and the SQL Performance Analyzer (ST04). These tools help analyze and optimize the performance of ABAP programs.
26. What is the purpose of the SQL Monitor in ABAP on HANA?
Answer: The SQL Monitor (transaction SM50/SM51) in ABAP on HANA allows you to monitor the SQL statements executed by ABAP programs, providing insights into their execution times and resource usage.
27. How do you perform data modeling using ABAP CDS views in ABAP on HANA?
Answer: Data modeling using ABAP CDS views involves defining entities, associations, and annotations in ABAP code using the CDS syntax. These views provide a semantic data model that can be consumed by other programs or applications.
28. What is the difference between an ABAP CDS view and a HANA CDS view?
Answer: An ABAP CDS view is defined in ABAP code and is part of the ABAP dictionary, while a HANA CDS view is defined using HDBDD files and is primarily used in native HANA development.
29. What are the different types of ABAP CDS views?
Answer: ABAP CDS views include basic views, composite views, consumption views, and analytical views. Each type serves a specific purpose and offers different capabilities for data modeling and reporting.
30. How do you enhance existing ABAP CDS views?
Answer: You can enhance existing ABAP CDS views using annotations, adding additional fields, or defining associations to other entities, providing additional functionalities or customizations.
31. What is the purpose of the ABAP Database Connectivity (ADBC) library in ABAP on HANA?
Answer: The ADBC library in ABAP on HANA provides a standardized interface for executing SQL statements and accessing database-specific features directly in ABAP code.
32. How do you perform error handling in AMDP methods?
Answer: Error handling in AMDP methods can be done using exception classes and exception handling techniques in ABAP, allowing for controlled error propagation and handling within the AMDP methods.
33. What is the purpose of the HDB-specific SQL functions in ABAP on HANA?
Answer: HDB-specific SQL functions in ABAP on HANA provide additional capabilities for working with data stored in the SAP HANA database, allowing for optimized data retrieval and processing.
34. How do you create and consume ABAP CDS table functions?
Answer: ABAP CDS table functions can be created using the CDS syntax and annotations. They can be consumed by other ABAP programs or applications using SQL or Open SQL statements.
35. What is the difference between an ABAP CDS table function and an ABAP CDS view?
Answer: An ABAP CDS table function returns tabular data and can be used as a data source in SQL statements, while an ABAP CDS view returns a result set and can be used for reporting or data access purposes.
36. How do you handle authorization checks in ABAP CDS views?
Answer: Authorization checks in ABAP CDS views can be implemented using the @AccessControl annotation, where you can define the required authorization objects and fields to control data access.
37. What is the purpose of the ABAP Test Cockpit (ATC) in ABAP on HANA?
Answer: The ABAP Test Cockpit (ATC) is a tool in ABAP on HANA that allows for automated code checks, performance optimizations, and adherence to coding guidelines, ensuring high-quality ABAP development.
38. How do you use the ABAP SQL Monitor to analyze performance issues?
Answer: The ABAP SQL Monitor allows you to analyze the performance of SQL statements executed by ABAP programs, providing insights into execution times, resource usage, and potential performance bottlenecks.
39. What is the purpose of the ABAP Managed Database Procedures (AMDP) in the context of authorization checks?
Answer: The AMDP framework provides support for performing authorization checks within the database layer, reducing data transfer and improving overall performance and security.
40. How do you enable and configure the ABAP Managed Database Procedures (AMDP) trace?
Answer: The AMDP trace can be enabled using the ABAP Development Tools (ADT) or the SAP GUI. By setting the trace level and enabling trace options, you can collect detailed information about the execution
