Use Predicate Naming for Boolean Methods (is_, has_, can_)

WarningClean ABAP & Modern Syntax#EC PREF_PRED_NAMERemote Enabled

Overview

Enforce predicate naming (IS_, HAS_) on boolean methods.

ATC Finding Message: Boolean-returning method should use predicate name (IS_, HAS_, CAN_)

Rationale

A boolean method reads best as a yes/no question, especially when it appears inside an IF condition. Names such as check_active or get_active leave the return type ambiguous and can suggest a side effect. Use is_, has_, or can_ prefixes for methods that return abap_bool.

Non-Compliant

METHODS check_active
  RETURNING VALUE(rv_active) TYPE abap_bool.

Compliant

METHODS is_active
  RETURNING VALUE(rv_active) TYPE abap_bool.
