Prefer INSERT ... INTO TABLE over APPEND

WarningClean ABAP & Modern SyntaxQuickFix Ready#EC INSERT_INTORemote Enabled

Overview

Prefer INSERT ... INTO TABLE over APPEND for table safety.

ATC Finding Message: Prefer INSERT ... INTO TABLE over APPEND

Rationale

APPEND only works for index tables and implies sequential insertion, so changing the table type to sorted or hashed later breaks the code. INSERT ... INTO TABLE works with every table category and states the intent generically. Use INSERT for table handling that should remain independent of the concrete table kind.

Non-Compliant

APPEND ls_order_item TO lt_order_items.

Compliant

INSERT ls_order_item INTO TABLE lt_order_items.
