Starting 22A, Oracle introduced a new field called “Employee Location”.

Any locations for which the value of the field will be selected as “Yes”, will be only available to be used in Manage Employment screen. This is a great feature to segregate locations which can be used on employee assignments vs locations which are used as training centers/ supplier locations etc.
By default, this field is hidden on Location Details quick action.
One needs to enable a sandbox and then from transaction design studio, make it visible.
From Quick actions under My Client Groups, choose Location Details:
If you still don’t see the attribute, create a new sandbox, add Experience Design Tool in it:
Choose Location Details as Action:
Click on Add,
under Page attributes, you see Employee Location is hidden OOTB:
P.S. – Please note this field can’t be used in classic locations page. Also, the default value is set to No.
