Prefer String Templates over CONCATENATE

Overview

Prefer string templates over CONCATENATE.

ATC Finding Message: Use string template |...| instead of CONCATENATE

Rationale

CONCATENATE with SEPARATED BY is a procedural statement that splits a message into literals and variables and cannot be nested in expressions. String templates interpolate values directly, preserve spaces, and support formatting options for numbers, dates, and alignment. Use a template for readable text composition and reserve CONCATENATE only for legacy downport code.

Non-Compliant

CONCATENATE 'Order' lv_order_id 'created' INTO lv_message SEPARATED BY space.

Compliant

lv_message = |Order { lv_order_id } created|.

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.

Suppression

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

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

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