How to have different buttons for different users on forms?

You will need to create two configurations instead using the username system.

Here you have the option via the edittext and the radiobuttons to make your configurations user-specific (making it possible to have one user who has one unique configuration, while another user has a different configuration).

The above screenshot result in that only the two users with usercodes “user1” and “user2” will see this configuration, while the screenshot below makes the configuration active to all other users except.

NB: It is your responsibility that a user does not overlap or is included in two or more configurations. If that is the case, the system will work with the first configuration it finds and ignore the additional configurations.
