6-10 years of experience in SAP - Interview question

Common Interview Questions and Sample Answers for SAP (6-10 Years Experience)

• Explain the Enhancement Framework in SAP ABAP.
  The Enhancement Framework enables extension of standard SAP applications without modifying the original code. It supports implicit and explicit enhancements, BADIs (Business Add-Ins), and enhancement spots for clean and maintainable customizations.

• How do you approach performance tuning of large ABAP reports?
  I start by analyzing SQL statements using tools like ST05 or SAT, optimize database access with proper indexing, minimize nested loops, and leverage parallel processing or HANA-specific features like CDS or AMDP views when applicable.

• Describe a scenario where you implemented a critical enhancement in a live SAP system.
  In a recent project, I added custom validation checks in the sales order process through a BADI implementation without affecting standard SAP functionality, ensuring business rules compliance while maintaining system stability.

• What strategies do you use to stay updated with SAP developments?
  I regularly follow SAP community forums, attend webinars, complete SAP release notes reviews, and participate in workshops. I also pursue certifications in new modules like SAP S/4HANA to keep my knowledge current.

• Explain how you develop a custom ALV report with interactive features.
  I use the ALV Grid Control with event handling to add sorting, filtering, and drill-down capabilities, ensuring a user-friendly and efficient reporting experience.

• How do you manage complex transport and change management processes?
  I maintain strict version control, test extensively in sandbox and QA environments, coordinate cross-functional releases, and use CTS+ tools for smooth changes across various SAP landscapes.

• What experience do you have in integrating SAP with external systems?
  I have implemented integrations using RFC, BAPI, and IDoc interfaces, ensuring secure and reliable data exchange between SAP and third-party applications.

• Can you explain the role of CDS views and AMDP in SAP HANA?
  CDS views provide semantic data modeling on the database layer, enabling efficient and reusable queries. AMDP allows writing database procedures in ABAP for native execution on SAP HANA, enhancing performance.

• How do you handle error handling and debugging in batch data communication (BDC) sessions?
  I log errors during session processing, analyze logs to identify root causes, correct input data or program logic, and reprocess the sessions ensuring data integrity.

• What are your best practices for modularization and reusable code in ABAP?
  I use function modules, classes, and interfaces to encapsulate logic, follow naming conventions, avoid code duplication, and document code for maintainability.
