Variable from User to Ticket


I would like to set an user field (select) I added,
to a field (maybe text, unchangeable) to a ticket.

Expected functionality:
Everytime the user, or the agent is creating a new ticket the info from the select field from the selected user should automatically be set to the ticket field but it needs to be unchangeable and just visible for the agent.

Is there any way to do this?

Thanks so far

Hi @sgrube287 ,

you could try to use core workflow for this:

As you can see it possible to set text fields readonly and to fill them up if another select field has been changed

My example is for a ticket but it is also possible to do this for the User object.

Thanks so far, this would be possible, but i have 100 selection possibilities.
to create 100 different workflows is unpractical.
