How to restrict a multiple users field to accept only one owner

To restrict a multiple users field and allow only one owner, open the field settings and turn on the option that limits selection to a single user per record — instead of the default that allows several at once.

Why does limiting this field matter?

In accounts with many users, leaving the field open to multiple selections can create confusion about who actually owns a process. A sales opportunity or a ticket without a single owner ends up with no one taking responsibility for resolving it.

The problem is even clearer on large teams: listing "all users" as the default option forces people to type out full names just to find who needs to be assigned.

How to configure the field

Open the multiple users field on the table you want.
Turn on the option to restrict it to a single owner.
Save — from then on, selecting a new name automatically replaces the previous one, instead of allowing two at the same time.

Behavior	Before	Now
Default selection	All listed users	You choose who shows up
Owner limit	Several at the same time	Only one, if configured that way

FAQ

What happens to records that already had more than one user?

They stay as they were until edited; the new rule applies to selections made after the change.

Can I switch back to multiple users later?

Yes, just turn off the restriction in the field settings whenever you want.

Does this setting apply to the whole account?

No, it's applied field by field, table by table, based on each process's needs. Learn more at jestor.com.
