Avoid Explicitly Raising System Exceptions (CX_SY_*)

WarningSecurity & Robustness#EC RAISE_CX_SYRemote Enabled

Overview

Avoid raising SAP internal system exceptions (cx_sy_*).

ATC Finding Message: Avoid raising SAP internal system exceptions; use application exceptions

Rationale

CX_SY_* exceptions describe failures detected by the ABAP runtime, such as invalid table access or division by zero. Applications should not fabricate those conditions because callers cannot distinguish them from real runtime faults. Define and raise a custom exception class for application errors instead.

Non-Compliant

RAISE EXCEPTION NEW cx_sy_zerodivide( ).

Compliant

RAISE EXCEPTION NEW cx_invalid_amount( ).

Suppression
