Limit Source Code Line Length (Avoid Horizontal Scrolling)

WarningMetrics & Complexity Limits#EC MAX_LINE_LENRemote Enabled

Overview

Maximum Line Length.

ATC Finding Message: Line length exceeds configured maximum limit

Rationale

Excessively long code lines (beyond 120 characters) force developers to scroll horizontally during code reviews and side-by-side Git diff inspections in Eclipse ADT and web repositories. Long lines also obscure trailing conditions and operators.

Clean ABAP Guideline: Wrap statements intelligently across multiple lines before reaching 120 characters, indenting subsequent continuation lines under the parent operator or assignment.

Non-Compliant

" Anti-pattern: 160+ characters stretching past standard monitor width
DATA(lo_order) = zcl_order_factory=>get_instance( )->create_from_request( is_request = ls_req iv_validate = abap_true iv_commit = abap_false ).

Compliant

" Clean ABAP: Formatted across logical continuation lines under 120 characters
DATA(lo_order) = zcl_order_factory=>get_instance( )->create_from_request(
  is_request  = ls_req
  iv_validate = abap_true
  iv_commit   = abap_false ).

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_LENGTH	Integer	120	Maximum allowed character length per source code line (industry standard: 120)
