Only Modify Tables Defined in Your Own Package/Component

WarningSecurity & Robustness#EC OWN_TABLESRemote Enabled

Overview

Modify Only Own Database Tables.

ATC Finding Message: Modify only customer-owned database tables (see OWN_TABLES)

Rationale

Writing directly to tables owned by another application component bypasses its validations, change documents, and authorization logic. It also creates an undocumented dependency that can break when the owning component evolves. Modify only tables in your own package and use released APIs for foreign data.

Non-Compliant

UPDATE mara SET matnr = @lv_matnr WHERE matnr = @lv_old_matnr.

Compliant

UPDATE zmara SET matnr = @lv_matnr WHERE matnr = @lv_old_matnr.

Configuration & Thresholds
