Avoid Deeply Nested TRY ... CATCH Blocks

WarningAnti-Patterns & Bad Practices#EC NESTED_TRYRemote Enabled

Overview

Avoid nested TRY blocks; extract to helper methods.

ATC Finding Message: Avoid nested TRY blocks; extract to dedicated method

Rationale

A TRY block inside another TRY block makes it unclear which handler owns which failure and often duplicates cleanup logic. The inner operation should have its own exception contract behind a method boundary. Extract it into a focused helper and keep one TRY per responsibility.

Non-Compliant

TRY.
  step1( ).
  TRY.
    step2( ).
  CATCH cx_step2_error.
    handle_step2( ).
  ENDTRY.
CATCH cx_step1_error.
  handle_step1( ).
ENDTRY.

Compliant

TRY.
  step1( ).
  execute_step2( ).
CATCH cx_step1_error.
  handle_step1( ).
ENDTRY.
