%tky

ABAP_USE
%tky is a component group in BDEF derived types and specifies the transactional key. A RAP BO instance must always be uniquely identifiable by its transactional key for internal processing during the RAP interaction phase.
%tky contains %key and the draft indicator %is_draft as components which makes it particularly suitable for draft scenarios. Since %tky includes %key, %tky can also be used in non-draft scenarios for referring to the primary keys. Its use in non-draft scenarios is even recommended as a preparation for a possible later switch to a draft scenario. In doing so, lots of adaptations to the code regarding the keys and the inclusion of %is_draft can be avoided.
ABAP_NOTE Moving %tky between two distinct types (for example, ...-%tky = ...-%tky) must be avoided to prevent errors. Instead, an expression with the component operator CORRESPONDING should be used, for example, ...-%tky = CORRESPONDING #(...-%tky).
