Sometimes you need to assign specific entries to specific users. In this case the "Select User" field type is helpful. Entries are typically managed by the entry creator who can edit an entry after the entry is created.
On the other hand, if the user normally does not have the necessary access rights to view records in one sheet, and you have to grant them access, you can use the "Set selected user as entry owner" attribute.
You can also assign an entry to the users in a user group, with the "Select Group" field type. This lists the groups of your account to choose from. If you choose "Set selected group as entry owner", all users in the group that is chosen as the value for this entry will have the same access right as the person who created this entry.
If the access rights for your sheet is set to "survey user", when you set a selected user as the owner of an entry, they can see this entry even if they aren't the creator.
If the access rights for your sheet is set to "bulletin user", when you set a selected user as the owner of an entry, they can edit this entry even if they aren't the creator.
This right can be revoked when the user or user group is removed from the field that sets the user as an entry owner.
Viewing all the users that can manage an entry can be done from the info panel in the bottom.
