Statement Indentation Must Match Block Nesting

WarningClean ABAP & Modern SyntaxQuickFix Ready#EC NO_BAD_INDENTRemote Enabled

Overview

Bad Statement Indentation.

ATC Finding Message: Statement indentation does not match block nesting

Rationale

Indentation is the fastest visual cue for block nesting, so inconsistent indentation misleads readers about which statements belong together. It also creates noisy diffs when a formatter runs. Indent each block level consistently.

Non-Compliant

METHOD calculate.
DATA lv_total TYPE i.
  LOOP AT lt_items INTO ls_item.
lv_total = lv_total + ls_item-amount.
  ENDLOOP.
ENDMETHOD.

Compliant

METHOD calculate.
  DATA lv_total TYPE i.
  LOOP AT lt_items INTO ls_item.
    lv_total = lv_total + ls_item-amount.
  ENDLOOP.
ENDMETHOD.

Automated QuickFix

This rule provides an automated QuickFix directly in Eclipse ABAP Development Tools (ADT):

1. Position the cursor on the flagged statement.
2. Press Ctrl + 1 (Quick Assist).
3. Select the automated refactoring to apply the clean syntax immediately.

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
INDENT_STEP	Integer	2	Standard indentation step per nested block level (default: 2 spaces)

Suppression

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

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

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