Limit Jump Statements (CONTINUE, EXIT) per Loop

WarningMetrics & Complexity Limits#EC MAX_LOOP_JUMPSRemote Enabled

Overview

Limit jump statements (CONTINUE/EXIT) per loop.

ATC Finding Message: Loop has too many jump statements (CONTINUE/EXIT); simplify loop control flow

Rationale

Loops containing too many jump statements (CONTINUE, EXIT) have convoluted control flow that makes loop invariants difficult to reason about and maintain. Restructure the loop body using helper methods or simplified boolean conditions.

Non-Compliant

LOOP AT lt_items INTO ls_item.
  IF cond1. CONTINUE. ENDIF.
  IF cond2. EXIT. ENDIF.
  IF cond3. CONTINUE. ENDIF.
ENDLOOP.

Compliant

LOOP AT lt_items INTO ls_item WHERE ...
  process_item( ls_item ).
ENDLOOP.

Configuration & Thresholds

This check can be fine-tuned directly in the ATC Check Variant Editor (CHKV) in Eclipse ADT:

Parameter Name	Data Type	Default Value	Description & Guidance
MAX_LOOP_JUMPS	Integer	2	Maximum number of jump statements (CONTINUE/EXIT) allowed per loop (default: 2)
