Fiori App - Need to Create a Fiori App that calls an HTML link with the user's SAP User Id embedded

We have a requirement where we want to add a Fiori Tile that links to an HTML link, but we need to add the Fiori users ID as part of the HTML link.

Is this possible? Does Fiori provide for global abap global variables and if so how can I capture the user ID and add it to the link as a variable?
