Check Downport Compatibility (7.40+ Modern Constructs)

WarningClean ABAP & Modern Syntax#EC DOWNPORT_COMPATRemote Enabled

Overview

Detect 7.40+ syntax incompatible with downport targets.

ATC Finding Message: Modern ABAP construct is incompatible with downport target release

Rationale

Modern ABAP constructs such as constructor expressions, table expressions, inline declarations, string templates, and functional method chaining do not compile on legacy NetWeaver releases. When a project must remain downport-compatible, these constructs silently raise the required kernel and syntax level. The check keeps that incompatibility visible by reporting each modern construct; it is disabled by default so modern development is unaffected.

Non-Compliant

DATA(lv_name) = lt_customers[ 1 ]-name.

Compliant

DATA lv_name TYPE string.
DATA ls_customer TYPE ty_customer.
READ TABLE lt_customers INTO ls_customer INDEX 1.
IF sy-subrc = 0.
  lv_name = ls_customer-name.
ENDIF.
