cap-defaultvalue-function

Common.DefaultValuesFunction pointed at a service function: getDefaultValues() selects the highest existing ID and returns that plus one, leaving the second key element to the user.

Books has a two-part key, ID and shop, with ID annotated @readonly so nobody types it. The entity is @odata.draft.enabled, the function is declared on the service beside it and annotated as the entity's Common.DefaultValuesFunction, and its handler orders Books by ID descending, takes the first row and returns { ID: ID + 1 }, so shop stays empty. An app under app/bookshop, listed in sapux, carries the generated field group and UI.LineItem annotations. One commit, from December 2024, and the README is the CAP scaffold's own getting-started text, so the annotation and that handler are the whole of it.
