Add an individual relationship attribute in Configuration.

If you want the same attributes available on the Spouse button as on the constituent record, add the same individual relationship attributes as in the constituent attribute.

If the constituent attribute uses a table as its data type, use the same table for the individual relationship attribute For more information on data types see

Note:  When querying, the constituent attribute and individual relationship attributes need to be selected separately, even if they share the same name and table.
