Prefer BETWEEN for Inclusive Range Checks

WarningClean ABAP & Modern Syntax#EC PREF_BETWEENRemote Enabled

Overview

Prefer BETWEEN for inclusive range checks.

ATC Finding Message: Combine the duplicated range comparison with BETWEEN

Rationale

lv_amount >= lv_min AND lv_amount <= lv_max repeats the same operand and spells out a single inclusive range. BETWEEN expresses the intent directly, removes the duplicated operand and makes off-by-one mistakes easier to spot. The rule only reports inclusive >=/<= pairs by default; strict >/< pairs are optional because they are not semantically equivalent for fractional values.

Non-Compliant

IF lv_amount >= lv_min AND lv_amount <= lv_max.
  approve( ).
ENDIF.

Compliant

IF lv_amount BETWEEN lv_min AND lv_max.
  approve( ).
ENDIF.

Configuration & Thresholds

This check can be fine-tuned directly in the ATC Check Variant Editor (CHKV) in Eclipse ADT:

Parameter Name	Data Type	Default Value	Description & Guidance
STRICT_RANGE	Boolean	false	Also suggest BETWEEN for strict >/< pairs, which is not equivalent for decimals (default: disabled)

Suppression
