Common standard features not working in RAP OData V4 - S4 2022 FPS02

[saurabh__khare38]

Hi,

I'm pretty new to RAP. We created a RAP-based app with a child entity and published it as an OData v4 UI binding. When previewing the service we noticed that a few standard features that work fine in a V2 binding are missing or do not work in the V4 binding. We even tried deploying the V4 binding, but the result is the same.

1. Missing back button(the small < icon on top left) on object pages. Also, notice that the title 'Invoice' is missing in V4

V2: 

V4: 

2. Missing table variant selection on child entity table

V2:

V4:

3. Error when navigating back (clicking on the parent entity) from the object page of the child entity. Also, notice the missing back button in V4.

V2:
/sap/bc/adt/businessservices/odatav2/feap?feapParams=nZ%5Dsi%5Ds%5Dbjc%5DWYscF77%5D%C2%82%C2%8A%C2%83%7Dwy77%C2%88%C2%83s%5D%C2%82%C2%8A%C2%83%7Dwy%5D%C2%88y%C2%81%C2%8777%5D%C2%82%C2%8A%C2%83%7Dwy%5D%C2%88y%C2%81%C2%8777nZ%5Dsi%5Ds%5Dbjc%5DWYscFsjUb77DDDE&sap-ui-xx-viewCache=false&sap-ui-language=EN&sap-client=200#/Invoice(InvUUID=guid'fbb22573-8615-1edf-858a-5b585fd1058e',IsActiveEntity=true)

V4:

/sap/bc/adt/businessservices/odatav4/Invoice(InvUUID=fbb22573-8615-1edf-858a-5b585fd1058e,IsActiveEntity=true)?restoreHistory=true

Are these known issues with V4? If not am I missing any required annotations in the MDE file? I assume not since the same MDE works fine when using OData V2. Kindly guide.

I found similar differences in my RAP Application as well. the one that bothered me the most is the Child Entity Object Page is not loading in V4 version, but it loads fine in V2 Version. Any expert comments/recommendations will be appreciated

Try deploying the app. I've found, deploying a V4 RAP app resolves almost all of these.

In BAS preview everything works fine - after deployment to SAP system I have exactly the mentioned issues. Additionally the restoreHistory call using the breadcrum is not working (File NOT exist). Any recommendations?
