Based on the following question RAP: Key As Segment capability support posted by Geert-Jan Klaps I found that I missed to blog about a nice “out-of-the-box” feature available for OData V4 services that lets a consumer use an alternate convention for addressing entities by appending a segment containing the unquoted key value to the URL.
This feature is described in the OData V.4.01 specification OData Version 4.01. Part 2: URL Conventions (oasis-open.org)
That means instead of
/sap/opu/odata4/dmo/ui_travel_proc_m_o4/srvd/dmo/ui_travel_processor_m/0001/Travel('1')
you can use the more REST like syntax
/sap/opu/odata4/dmo/ui_travel_proc_m_o4/srvd/dmo/ui_travel_processor_m/0001/Travel/1
it even works with navigation so that you can use the following URL as well:
/sap/opu/odata4/dmo/ui_travel_proc_m_o4/srvd/dmo/ui_travel_processor_m/0001/Travel/1/_Booking/2
This feature works for OData V4 services based on the ABAP RESTful Application Programming Model but also for services based on a code based implementation based on the SAP Gateway OData V4 framework when using the latest SP of SAP_GWFND.
