Clean ABAP
What it is
SAP's open-source style guide for readable, maintainable ABAP (the ABAP take on 'Clean Code'). It covers naming, method size, error handling, and modern syntax preferences.
Why it matters for Clean Core
Clean ABAP is the readability counterpart to Clean Core: cloud-ready code is also code humans (and SAP's AI) can follow. The two reinforce each other — modern syntax is both cleaner and more likely to be cloud-allowed.
Common pitfall
Treating it as cosmetic. Several Clean ABAP rules (avoid obsolete statements, prefer inline declarations, use exceptions not sy-subrc sprawl) directly overlap with what the Cloud Development language version requires.
