Limit Line Length

WarningMetrics & Complexity Limits#EC LINE_LENRemote Enabled

Overview

Maximum Line Length.

ATC Finding Message: Line length exceeds configured maximum limit

Rationale

Lines longer than the configured limit force horizontal scrolling and hide parts of a statement in review tools. They also encourage dense expressions that are hard to debug. Break statements at logical operators and use short, meaningful names.

Non-Compliant

lv_result = lo_service->calculate_total_with_discount_and_tax_for_customer( iv_customer_id = lv_customer_id iv_currency = lv_currency ).

Compliant

lv_result = lo_service->calculate_total_with_discount_and_tax_for_customer(
  iv_customer_id = lv_customer_id
  iv_currency    = lv_currency ).

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
MAX_LENGTH	Integer	120

Suppression

To suppress findings for this rule, append the pseudo-comment to the statement:

" Standard pseudo-comment:
... "#EC LINE_LEN

" SAP CI_ prefix format:
... "#EC CI_LINE_LEN
