How to Customize the Profile in Business Central On premise

Hi community,

Is it possible to customize the top-right profile username display in Business Central On-Premises?

My idea is to create a custom mapping table in AL that maps the Windows login to a friendly display name, for example:

DOMAIN\user01 → Koko
or DOMAIN\user01 → Dex

But I am not sure if the top-right profile area can read from a custom table or if it is locked to the Windows login name.

Has anyone done something like this before?

Thank you!

Hello,

No, you can’t customize that top-right username display—it's controlled by the authentication layer (Windows/Entra/NavUserPassword) and rendered by the web client shell, not by AL or page/profile customization, so it always reflects the signed-in user identity and won’t read from a custom mapping table; the only way to change what appears there is by changing the underlying user/account setup outside AL, not inside Business Central.
