To select multiple records Multiple Selection check box should be checked.
Shows the cross-reference records for the record that is selected in the Instances for list.
The records from the source system are pooled to form a record known as the cross-reference records.
Cross-reference records that are created by manual edits can be removed from the base object.
The existing cross-reference table also contains the pending cross-references. They are distinguished from others by marking as PENDING and showing in a different color.
Displays a list of the base object columns. Each base object column has the following properties.:
Column Name: Name of the column.
Trust: Current trust level associated with the column value from the selected base object.
Base Object Cell: Column value from the selected base object.
Cross-Reference Cell: Column value from the selected cross-reference row.

Whereas, the related row in the cross-reference table is restored as its own base object row. Also, the current base object is freed from the control of that row on it.
Tree Unmerge: Perform a tree unmerge on a cross reference from the selected base object. At the time of a tree unmerge, a whole set of merged base object records turn out to be unmerged from the original structure into an intact substructure.
