setSemanticStepName not working for UI5 Web Components (FESR step name not overridden)

[nainagodhwani]

Bug Description

We are implementing telemetry for our application and using the setSemanticStepname function from FESRHelper:
The goal is to assign meaningful semantic step names to user interactions so that they are reflected correctly in FESR logs when validated using the FESR EPP Chrome Extension.

import FESRHelper from "sap/ui/performance/trace/FESRHelper";

When a custom step name is set via:

setSemanticStepName(item, "click", FESRStepNames.SETTINGS_BUTTON_CLICK);

the expectation is that the provided semantic step name appears in the FESR logs after deployment.
This works correctly for classic SAPUI5 controls such as sap.m.Button.

However, when the interaction originates from UI5 Web Components, the semantic step name is not applied. Instead, the FESR logs continue to display the auto-generated FESR name's (for example, r360::GoButton_click).

No error is thrown, but the custom semantic step name is ignored.

As a result, it becomes challenging to capture meaningful semantic telemetry in Web Component–based applications.

Affected Component

No response

Expected Behaviour

setSemanticStepName (or equivalent semantic step override mechanism) should work consistently for interactions triggered by UI5 Web Components.

When a semantic step name is set during a Web Component click/interaction, the FESR STEP_NAME should reflect the provided custom value instead of the auto-generated technical interaction name.

Isolated Example

No response

Steps to Reproduce

1. Launch the application that uses UI5 Web Components.
2. Install and enable the FESR EPP Chrome Extension
3. Open the browser Developer Tools and navigate to the FESR extension panel.
4. Trigger the relevant user interaction in the application.
5. Observe the recorded STEP_NAME in the FESR logs.

Hi, I tried to reproduce this issue and couldn't replicate it - FESRHelper.setSemanticStepname() works correctly for UI5 Web Components in both local development and production build.

My configuration:

• UI5 version: 1.131.1
• UI5 Web Components: 2.16.2
• @ui5/cli: 4.0.8
• ui5-tooling-modules: 3.34.0
• Web Components consumed via: xmlns:web="@ui5/webcomponents"
• FESR enabled via: data-sap-ui-fesr="true" in bootstrap

Tested scenarios:

• ✅ Local development (ui5 serve)
• ✅ Production build (ui5 build --all + ui5 serve --config ui5-dist.yaml)

Both show the correct custom STEP_NAME in FESR logs.

Since you mentioned this happens after deployment, could you provide more details about your setup?

• What version of @ui5/cli are you using?
• What version of ui5-tooling-modules are you using?
• Are you deploying to SAP BTP / Cloud Foundry?
• Is the app running inside Fiori Launchpad (FLP)?
• Is UI5 loaded from CDN or bundled with the app?
• What UI5 version is loaded at runtime in the deployed environment?

This might help narrow down whether the issue is related to a specific deployment configuration or tooling version.

Hi @nainagodhwani

thanks for sharing your environment.

Is there a chance to test with latest ui5-tooling-modules, 1.16.5 is pretty old?

BR,
