Adaptation editor for SAPUI5 adaptation project with VS Code - On Prem

[SDJEMAA]

Hello everyone,

I’ve created a UI5 adaptation project using the new Adaptation Editor generator (from the latest UI5 tooling update).

The project generation and build completed successfully without any errors.

However, when I try to preview or open the Adaptation Editor from my variant, the browser launches but:

• The application does not render (blank page).

• No UI5 controls or components are loaded.

• The console doesn’t show any clear errors related to UI5 modules, but the app never initializes.

Here’s what I’ve done and verified so far:

1. Generated the adaptation project via the new generator (https://www.npmjs.com/package/@sap-ux/generator-adp)

2. file .variant structure are correctly created.

3. Verified that the base application loads normally outside of the adaptation project.

4. Tried different browsers and cleared the cache — same result.

Question:

1. Has anyone experienced this behavior with the new Adaptation Editor generator ?
2. Is there any known configuration or dependency missing to make the preview work properly ?

Any insights or troubleshooting steps would be greatly appreciated.

The application is F3172. The sap-ui.core.js file doesn't seem to be retrieved correctly. However, I downloaded the resources and test-resources folders from UI5 SDK.

Hi, I have try the scenario locally and it is working fine. Can you please specify with which SAPUI5 version you are starting the Editor? Also once the Editor starts, open the browser console and then reload the browser page and check the network tab and the console for errors. May be the oData is not loaded that's why you see blank page. It is possible that the used user doesn't have enough roles or rights.

Hello, I have these errors in the console when I do the adaptation editor :

[SDJEMAA]

The version used is 1.120.14 for SAPUI5

[Gergana_Marcheva]

Looks like a problem with the ui5 version. Please change it to 1.108.47 in the ui5.yaml file (on the very bottom of the file).

[SDJEMAA]

The version of SAPUI5 should not be aligned with the SAP_UI component in the S/4 system used ?

[Gergana_Marcheva]

As a general rule yes, because there might differences in the available features but sometimes since the app is loaded FLP sandbox one might need to change the version up or down so the editor can work. Otherwise once the app is deployed it works with the UI5 version that is on the system.

[SDJEMAA]

If I want to make a change without preview/adaptation editor, is this possible ? If so, how ?

[junwu]

why you have that idea?

[SDJEMAA]

This is to determine whether there is a workaround or not.

Hi SDJEMAA,

Adaptations can also be made via Runtime Adaptation (https://help.sap.com/docs/UI_ADD-ON_FOR_SAP_NETWEAVER_20/17ae0e97e0fc424a9c368f350c0ba6bd/5c424437bf...) but those changes are basic one, for example hide a field or rename a label. But for example you can't extend the controller or add a fragment.

Otherwise I don't understand why you want to change the approach. If the Adaptation Editor works with the suggested from me version then just use it that way. As I said that version is only for the Editor. Once the app is deployed it will use the version that is on your system and it will work as expected since the app there is not working in FLP sandbox. You can simply try making some changes, deploy the app and test it there.

 Best Regards,

Gery

Ok thanks for your reply.

[junwu]

which app?  did you check vsc terminal?

[SDJEMAA]

app f3172

[junwu]

the ui5 version doesn't matter that much concerning the version you have in your onpremise system.but if the ui5 you specified is not available in the internet, your project won't run.
