Keep this: job aid

Advanced RAP card

• Draft: with draft (whole BO), draft table per entity, total etag on root; Edit, Activate optimized (runs Prepare), Discard, Resume, Prepare.
• Use %tky (includes %is_draft) in handlers and EML.
• Feature control: FOR INSTANCE FEATURES / FOR GLOBAL FEATURES; "can it happen?".
• Authorization: master (global, instance) on root; children dependent; "may you do it?"; reads via CDS access control.
• Block activation with validations; prechecks stop requests before the buffer; IN LOCAL MODE skips checks.
• Side effects: trigger (field, action, determine action, $self, event) affects fields, entities, permissions, messages; no ABP code.
• Events: declare in root BDEF; RAISE ENTITY EVENT in save_modified (with additional save); event binding; idempotent, monitored consumers.
• Test: ABAP Unit + EML with CDS/SQL doubles and @testing relation; consumers with buffer double or mock EML; UI and end-to-end for side effects, locks, delivery, access control.
