Avoid Hungarian Notation and Type Prefixes

WarningClean ABAP & Modern Syntax#EC NO_HUNGARIANRemote Enabled

Overview

Avoid Hungarian notation and encoding prefixes.

ATC Finding Message: Avoid Hungarian notation and encoding prefixes in names

Rationale

Hungarian notation prefixes (such as lv_, ls_, lt_, mv_, iv_, rv_) add visual clutter, encode technical types that frequently change, and conflict with modern Clean ABAP principles. Name variables and parameters after their domain meaning instead.

Non-Compliant

DATA lv_count TYPE i.
DATA mv_value TYPE string.
METHODS process IMPORTING iv_input TYPE string.

Compliant

DATA count TYPE i.
DATA value TYPE string.
METHODS process IMPORTING input TYPE string.

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
CHECK_ATTR	Boolean	true	Report legacy Hungarian notation type prefixes on class attributes
CHECK_LOCAL	Boolean	true	Report legacy Hungarian notation type prefixes on local variables
CHECK_PARAM	Boolean	true	Report legacy Hungarian notation type prefixes on method parameters

Suppression

To suppress findings for this rule, append the pseudo-comment to the statement:

" Standard pseudo-comment:
... "#EC NO_HUNGARIAN

" SAP CI_ prefix format:
... "#EC CI_NO_HUNGARIAN
