Hello,
If you check any field as ID field, then this will be used as primary key which uniquely identify the item in the domain. If you select multiple filed as ID fields, then values of all selected IDs fields, are combined to form the primary key.
When you list the domain, the first column SDB-Item-Name shows these primary keys for all listed items.
