ABAP Performance Tuning & Optimization Mastery with Aditya Gupta

ABAP Performance Tuning & Optimization Mastery

The Complete Practitioner's Guide — From Fundamentals to Advanced HANA Code-Pushdown

Why This Book Exists

Every SAP ABAP consultant eventually hits the same wall: code that works perfectly in testing grinds to a halt in production. A report that runs in 2 seconds for 100 records takes 40 minutes for 2 million. A background job blows past its batch window. A "simple" nested loop silently becomes an O(n²) disaster the moment real data volume hits it.

This book exists to close that gap — between knowing ABAP syntax and knowing how to make ABAP fast, scalable, and production-ready.

Written as the single reference you keep open on your second monitor, this guide takes you from the fundamentals of the ABAP runtime all the way to HANA-era code pushdown, with real project scenarios and interview preparation woven into every chapter — not bolted on as an afterthought.

What You'll Learn

• The ABAP runtime and memory model — work processes, extended memory, roll area, and why certain patterns cause dumps like TSV_TNEW_PAGE_ALLOC_FAILED
• The complete performance analysis toolbox — SAT, ST05, ST12, SM50/SM66, ST22, ST02, and Code Inspector/ATC, with step-by-step walkthroughs
• Open SQL mastery — the five deadly anti-patterns, JOIN vs. FOR ALL ENTRIES decision-making, index design, and table buffering
• Internal table optimization — STANDARD vs. SORTED vs. HASHED, secondary keys, field-symbols, and the classic nested-loop explosion
• The Parallel Cursor Technique — the algorithmic optimization every senior interviewer asks about, explained with a full worked example
• Advanced topics — parallel processing frameworks, CDS views, AMDP, ABAP-on-HANA code-to-data paradigm, locking/enqueue performance, and ALV/Smart Forms tuning
• 12 real project case studies — actual situation → root cause → fix → measured outcome, covering billing runs, Fiori timeouts, memory dumps, RFC flooding, and more
• 11 hands-on exercises — with full worked solutions, so you practice every concept instead of just reading about it
• 150+ interview questions — organized from basic definitions through architect-level scenario discussions, exactly as they're asked in real ABAP developer and senior consultant interviews

Who This Book Is For

• ABAP developers and consultants preparing for performance-critical project work or interviews
• Technical architects who need to review designs for performance risk before code is written
• Support/AMS consultants troubleshooting live production incidents
• Job seekers preparing for SAP technical interviews at any level — from junior developer to senior architect

What Makes This Book Different

Most ABAP resources either teach syntax (without teaching when and why to use it) or list interview questions with no depth behind the answers. This book does both: every concept comes with a "bad vs. good" code comparison, a real-project insight box explaining why it matters in practice, a hands-on exercise to test your understanding, and matching interview questions so you can defend your knowledge under pressure.
