Order Declarations (TYPES, CONSTANTS, DATA)

WarningClean ABAP & Modern Syntax#EC DECL_ORDERRemote Enabled

Overview

Enforce declaration order (TYPES, CONSTANTS, DATA, FS).

ATC Finding Message: Declare local TYPES before CONSTANTS before DATA before FIELD-SYMBOLS

Rationale

Declarations in arbitrary order make dependencies hard to follow and can place a DATA declaration before the TYPE it uses. A stable order of TYPES, CONSTANTS, then DATA gives readers a predictable structure. Group declarations by kind at the top of the routine.

Non-Compliant

METHOD execute.
  DATA lv_count TYPE i.
  TYPES ty_status TYPE c LENGTH 1.
  CONSTANTS c_init TYPE ty_status VALUE 'I'.
ENDMETHOD.

Compliant

METHOD execute.
  TYPES ty_status TYPE c LENGTH 1.
  CONSTANTS c_init TYPE ty_status VALUE 'I'.
  DATA lv_count TYPE i.
ENDMETHOD.
