You want to restrict end user activities for an application.

The SAP Fiori Apps Reference Library is a comprehensive online library of all available SAP Fiori apps. It provides information about the app features, technical data, configuration, and implementation. You can use the SAP Fiori Apps Reference Library to look up the business catalog(s) that grant access to an app by following these steps:

Go to the SAP Fiori Apps Reference Library website and log in with your SAP credentials.

In the search bar, enter the name or ID of the app you want to restrict access to, and click the search icon.

In the search results, click on the app tile to open the app details page.

On the app details page, scroll down to the Implementation Information section and expand the Configuration tab.

Under the Configuration tab, you will see the Business Catalog field, which lists the business catalog(s) that contain the app. You can click on the business catalog ID to view more details about it, such as the business roles, business groups, and other apps that are assigned to it.
