Splitting Related Sibling Records
You can split one or more related records in a sibling relationship into a new sibling group as described in this section.
To split one or more related records into a new sibling group:
1. If necessary, click on the tab for the sibling relationship whose related records you want to split to make it the active tab.
2. In the Sibling grid, select the records you want to split into a new sibling group.
3. Right-click on one of the records and choose Split from Relationship from the context menu, or choose Relationships ® Split from Relationship from the main menu.
MDM splits the related records into a new sibling group and removes them from the grid, unless the anchor is one of the selected records, in which case, the unselected records are removed from the group.
