Avoid Boolean Flag Importing Parameters

WarningClean ABAP & Modern Syntax#EC NO_BOOL_BLINDNESSRemote Enabled

Overview

Avoid boolean flag importing parameters.

ATC Finding Message: Boolean importing parameters hide intent; use dedicated methods or a typed flag

Rationale

A boolean importing parameter turns a method call into a positional switch: callers write do_work( abap_true ) and readers cannot tell what true means without opening the signature. Boolean blindness also pushes every new variation into the same method instead of a dedicated, well-named API. Expose the alternatives as separate methods or as a meaningful typed flag, and keep abap_bool flags out of method interfaces.

Related Rules

• Use Predicate Naming for Boolean Methods (is_, has_, can_) — #EC PREF_PRED_NAME
• Avoid Comparing to abap_true / abap_false — #EC NO_BOOL_COMPARE
• Limit Method Parameter Count and Require Multi-Line Signatures — #EC MAX_PARAMS_COUNT
