Prefer the Short System Field Alias SY over SYST

WarningClean ABAP & Modern SyntaxQuickFix Ready#EC PREF_SYRemote Enabled

Overview

Prefer the short system field alias SY over SYST.

ATC Finding Message: Use sy- instead of syst- for system fields

Rationale

SYST and SY address the same system structure, so mixing both aliases makes code look inconsistent and complicates searching. SY is the conventional short form used throughout Clean ABAP. Use sy- consistently for system field access.

Non-Compliant

lv_user = syst-uname.

Compliant

lv_user = sy-uname.
