Enforce Class Attribute and Method Parameter Naming Conventions

WarningClean ABAP & Modern Syntax#EC PREF_NAME_MEMBERSRemote Enabled

Overview

Class Attribute and Parameter Naming Conventions.

ATC Finding Messages:

• Class attribute name does not match configured pattern
• Method parameter name does not match configured pattern
• Selection screen element name does not match configured pattern

Rationale

Member variables and method signatures communicate the contract of object-oriented components. Enforcing prefixes (mv_* for instance attributes, gv_* for static attributes, iv_* for importing, ev_* for exporting, cv_* for changing, and rv_* for returning parameters) clarifies usage semantics across callers.

Non-Compliant

METHODS execute
  IMPORTING data TYPE i
  RETURNING VALUE(result) TYPE i.

Compliant

METHODS execute
  IMPORTING iv_data TYPE i
  RETURNING VALUE(rv_result) TYPE i.

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
ATTR_IGN_EXC	Boolean	true	Ignore exception class attributes (cx_*)
ATTR_IGN_LOCAL	Boolean	true	Ignore attributes in local test classes
ATTR_IGN_INTF	Boolean	false	Ignore interface component naming
ATTR_STATICS	String	^G._.+$	Regex pattern for static class attributes (default: ^G._.+$)
ATTR_INSTANCE	String	^M._.+$	Regex pattern for instance class attributes (default: ^M._.+$)
ATTR_CONSTANTS	String		Regex pattern for class constants (default: ^C._.+$)
PARAM_IGN_EXC	Boolean	true	Ignore parameter naming in exception classes
PARAM_IMPORTING	String	^I._.+$	Regex pattern for importing parameters (default: ^I._.+$)
PARAM_RETURNING	String	^R._.+$	Regex pattern for returning parameters (default: ^R._.+$)
PARAM_CHANGING	String	^C._.+$	Regex pattern for changing parameters (default: ^C._.+$)
PARAM_EXPORTING	String	^E._.+$	Regex pattern for exporting parameters (default: ^E._.+$)
SSCR_PARAM	String	^P_.+$	Regex pattern for selection screen parameters (default: ^P_.+$)
SSCR_SELOPT	String	^S_.+$	Regex pattern for select-options (default: ^S_.+$)
