Coding standards
Quick answer
Custom code runs in the hottest paths and is what breaks on upgrades.
Key takeaways
- Follow performance rules (no SELECT-in-loop; efficient internal tables).
- Write object-oriented, small, single-purpose methods; clear naming.
- Be null-safe and handle errors via class-based exceptions.
- Watch out: Skipping the discipline under delivery pressure.
Key practices
- Follow performance rules (no SELECT-in-loop; efficient internal tables).
- Write object-oriented, small, single-purpose methods; clear naming.
- Be null-safe and handle errors via class-based exceptions.
- Write ABAP Unit tests; use static checks (ATC/Code Inspector).
- Extend, don’t modify, standard, use enhancements/BAdIs and clean-core techniques.
Why it matters
Custom code runs in the hottest paths and is what breaks on upgrades. Disciplined, tested, clean-core-compliant code is far easier to maintain, performs well, and survives upgrades, the difference between an asset and a liability.
Common pitfalls
- Skipping the discipline under delivery pressure.
- Not documenting decisions.
- Ignoring the clean-core principle.
