I am working on a Fiori app which connects to a on-premise backend system through Cloud Connector. I am creating new Odata service in the gateway system through SAP GUI and I have created database tables and ABAP structures for the service. One main requirement for the app is that as this app will have read/write/edit/delete functionality, there should be such a functionality that allows only people who submitted entries to edit their own entries as well as a custom (editable) list of individuals who can edit/delete any entry. We are using SAP data services. It would be great if I could get some guidance on how I can achieve such a functionality. I know this question is a bit vague but I am just starting with SAP development and any general guidance would be of great help!
Thanks in advance :)
