Avoid Using ABAP Keywords as Identifier Names

Overview

Avoid Using ABAP Keywords as Identifier Names.

ATC Finding Message: Identifier name matches an ABAP keyword

Rationale

Using a language keyword such as class, type, or data as an identifier shadows the keyword and forces readers to disambiguate from context. It also complicates searching and can confuse tooling. Prefix identifiers with their role, for example lv_type.

Non-Compliant

DATA interface TYPE string.
DATA report TYPE i.

Compliant

DATA lv_interface TYPE string.
DATA lv_report TYPE i.

Suppression

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

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

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