Hi Team, 
 I have a requirement where I should not display test.admin user in suggestion 
 This is my current condition which I have implemented to restrict a user, but it still displays the user in suggestion 
 Users from Appian Directory, ri!user : User (Type) 
 a!pickerFieldUsers( label: "Select User", maxSelections: 1, value: if(ri!user = "test.admin", {}, ri!user), saveInto: ri!user, 
 required: true, ), 
 Could someone please help us on this.

Hi grandhiritusha Create a group, add the required users to it, and pass the group to the groupFilter parameter in a!pickerFieldUsers() using a constant.

You can use the groupFilter feature, or create a custom picker field based on your specific requirements which users to show.
