Assign default value to field in Fiori Elements

[robmamba25]

Can a default value be assigned to a field on an object page in the create option from the front-end in SAP Fiori Elements?

The following options are available for prefilling some values in the backend service. Not suitable if you are looking for a way to supply default values from the frontend app, though.

I need to do it from the frontend since I need to get the user (sap.ushell.Container.getService("UserInfo")) from the IAS to set it in a field that is the requisitioner name in a requisition

But you have this user also available also in the backend.

How would that be? Or how could I do it?

It depends on where your frontend and backend apps are hosted. For example, if both frontend and backend apps are hosted on an ABAP server, you can get the logged-in user from the sy-uname variable.
