You have assigned a business role to an end user who has been granted access...

Comprehensive and Detailed Explanation From SAP S/4HANA Cloud Public Edition, Management Accounting documents:31

If an app is authorized but not visible on the launchpad, it is often due to missing layo32ut assignments33.

Assign a Space: A business role must have at least one launchpad space assigned to display apps as tiles; without a space and page, the tiles won't appear even if authorizations are correct34343434.

Search Function: Even if the tile is missing, the user can locate and launch the app via the launchpad's Search or App Finder tool, provided they have the correct business role permissions35353535.

End users do not have permissions to create their own pages or assign different roles to themselves36.
