OData Service for Create Purchase Order APP

Hi All,

The Basis team has installed a Fiori APP: "Create Purchase Order('ME21N')" .: Application type: SAP GUI

However, I am not able to find the OData service corresponding to the APP.

I have checked in the link https://fioriappslibrary.hana.ondemand.com/sap/fix/externalViewer/#/detail/Apps('ME21N')/S8OP as well, but no mention of OData service.

Is there any other way to Find the OData service for the APP installed above.

Thanks and Regards
