RFC calls must handle SYSTEM_FAILURE and COMMUNICATION_FAILURE

ErrorSecurity & Robustness#EC RFC_ERRRemote Enabled

Overview

RFC calls must handle system failures.

ATC Finding Message: RFC call must handle SYSTEM_FAILURE and COMMUNICATION_FAILURE

Rationale

A remote function call can fail because the target system is unavailable or the communication layer breaks, independently of the function logic. Without handlers for SYSTEM_FAILURE and COMMUNICATION_FAILURE, these failures become unhandled dumps or silent errors. Always handle both, plus OTHERS, and evaluate the response.

Non-Compliant

CALL FUNCTION 'Z_RFC'
  DESTINATION lv_rfc.

Compliant

CALL FUNCTION 'Z_RFC'
  DESTINATION lv_rfc
  EXCEPTIONS
    system_failure        = 1 MESSAGE lv_message
    communication_failure = 2 MESSAGE lv_message
    OTHERS                = 3.
