Avoid LIKE Typing on Global Dictionary Objects

WarningAnti-Patterns & Bad Practices#EC LIKE_OBJECTSRemote Enabled

Overview

Avoid LIKE referencing data objects; use explicit TYPE.

ATC Finding Message: Avoid LIKE for data declarations; specify TYPE explicitly

Rationale

LIKE copies the type of a data object, which couples the new declaration to an implementation detail rather than to a type contract. For Dictionary objects, TYPE references the type directly and stays stable when the referenced object changes. Use LIKE only for local data objects whose type is intentionally shared.

Non-Compliant

DATA lv_material LIKE mara-matnr.

Compliant

DATA lv_material TYPE mara-matnr.
