Do we Change UI5 version after S/4HANA Upgrade ?

[former_member182874]

Hello,

It's an ideal situation when your company wants to upgrade your S/4 version from old to new/latest.

For my scenario : We have upgraded our system from 1709 to 2021 version. So our UI5 library version has been upgraded from 1.71.11 to 1.96.7 .We are now on SAP_UI - SAPK-75604INSAPUI.

We have more than 40 custom UI5 apps or Fiori-like apps based on Fiori elements. The app versions which were deployed before was as per system version 1.71.11.

Now the system UI5 version has been changed to 1.96.7. Do I need to change the version of each app manually in webide and re-deploy to my frontend to match the System UI which is 1.96 or I can leave them as it is.

There are no issues in my custom apps as of now. But as per recommendation there might be many libraries which may be deprecated or upgraded.

1. How do you guys deal with this situation ?

2. Is there any automated tool to change the UI5 version for each custom apps ?

3. I have seen some old blogs(dated 2015) but seems they are not valid anymore after newer releases of S/4HANA

PS : I know how to change the ui5 version in webide. Just asking if it is required to change everytime we upgrade to latest ui5 version. Is this a normal practice in every project ?

Hi Tejas,

I would say you don't need to adjust the deployed apps. If you run them all as components in the Embedded Launchpad they will directly use the UI5 coming with the new S/4HANA.

But regarding Web IDE I would think about two things:

1. You might want to think about switching to SAP BAS or directly to local development with VS Code and the Fiori Tools
2. If you not yet use the UI5 tooling it might also be a good point to migrate now. In this step you can then also adjust the UI5 version to match your S/4HANA UI5 version

Best Regards

Hi Gregor,

Thank you for your response.

If you run them all as components in the Embedded Launchpad : By this statement do you mean that apps deployed to Fiori launchpad ?

Regarding BAS, yes I will switch to BAS in upcoming developments. 🙂

Yes I noticed that when i check the UI5 version in console. It is showing the UI5 version coming from my frontend.

Yes, I mean that you do not run them standalone with an index.html that might point to the CDN.

ui5 app has no ui5 version for you to change. no such thing.

the app will just take whatever version of ui5 lib you provide to run
