Top 10 SAP ABAP Interview Questions - You Must Know Them
1. What is the Role of the ABAP Data Dictionary?
The ABAP Data Dictionary is the central hub for managing metadata in an SAP system. It stores details about database objects like tables, views, structures, data elements, and domains. Developers use the graphical interface (SE11) to create, modify, and maintain these objects, ensuring data consistency across the system. Additionally, the Data Dictionary enforces referential integrity, supports data types, and provides APIs for programmatic access, making data management more structured and efficient.
2. What is the Difference Between Transparent Tables and Pooled Tables?
- Transparent Tables: These have a one-to-one mapping with the database. Each transparent table corresponds directly to a database table and is used for storing application data. They can be accessed via SQL queries.
- Pooled Tables: These have a many-to-one relationship with the database. Several pooled tables are stored within a single table pool at the database level. They are mainly used for internal data like configuration settings and are accessed using function modules.
3. What is BDC (Batch Data Communication) in ABAP?
BDC is an automated process for transferring large volumes of external data into SAP. It works through batch input programs, which store data in a queue file and process it in sessions. This method eliminates the need for manual data entry, making it an efficient way to migrate data into SAP.
4. What are the different Data Classes in SAP ABAP?
ABAP classifies data into four main types:
- Master Data: Information that rarely changes, like customer or vendor records.
- Transaction Data: Frequently changing data, such as sales and purchase orders.
- Organization Data: System configuration data that remains mostly static.
- System Data: Internal SAP data used for system operations.
5. What Are Internal Tables in ABAP?
Internal tables are temporary storage structures used during program execution. They help in manipulating, sorting, and processing data without affecting the actual database. Defined using the DATA statement, they allow efficient handling of large datasets in memory.
6. What Functional Modules Are Used in BDC?
BDC follows a sequence of function modules for successful data transfer:
- BDC_OPEN_GROUP: Initiates a batch session, specifying details like client, user, and session name.
- BDC_INSERT: Inserts transaction data into the session.
- BDC_CLOSE_GROUP: Closes the batch session after processing.
7. What Is a Foreign Key Relationship in ABAP?
A foreign key relationship ensures data consistency between two tables by linking a field in one table to a corresponding field in another. It prevents invalid data entries by enforcing referential integrity. When defining a foreign key, cardinality is specified to indicate the number of dependent and referenced records allowed.
8. What Are the Different Types of Views in ABAP?
SAP ABAP provides four main types of views:
- Database View: Uses INNER JOINs to combine data from multiple tables and behaves like a physical table.
- Projection View: Focuses on specific fields of a single table, limiting data visibility for simplicity.
- Help View: Supports search helps by using OUTER JOINs to retrieve data from multiple tables.
- Maintenance View: Enables easy maintenance of related tables by allowing data creation, modification, and deletion.
9. What Is an ALV Report and How Is It Created?
An ALV (ABAP List Viewer) report enhances data presentation in SAP by providing features like sorting, filtering, and interactive display. To create an ALV report:
- Populate an internal table with data.
- Define a field catalog that structures the ALV grid.
- Use the function module REUSE_ALV_GRID_DISPLAY to generate the report.
10. How Do You Handle Errors and Exceptions in ABAP?
ABAP provides structured error handling using TRY, CATCH, and ENDTRY statements. The TRY block contains the code that might throw an exception, while the CATCH block manages error handling or recovery. Developers can catch specific exceptions or use the CX_ROOT class to handle all exceptions. Additionally, debugging tools like the ABAP Debugger and runtime analysis help identify and resolve errors efficiently.
