If you have many DHLinks to review, you can select DHLink Summary from the DataHub menu to open the Cameo DataHub DHLink Summary dialog and view all types of links. In the DHLink Summary dialog, you can filter the relations that you want to view and adjust the display. You can also remove or update a relation, or clear the status.
There are two filter options: No DHLink and DHLink. The No DHLink option filters all elements that have no DHLink element in the DataHub, and the DHLink option filters all elements that contain DHLink synchronization.
To open the DHLink Summary dialog
- On the MagicDraw main menu, click Tools > DataHub > DHLink Summary.
- The DHLink Summary dialog opens. The Filter Options pane on the left-hand side allows you to choose what type of relations you want to see. You can select one of the following:
- No DHLink to display independent standalone elements and nodes without any DHLink.
- DHLink to display the relation between elements. The state of the DHLink could be Synchronized, Orphan, Pending Delete, Pending Update, or Excluded.
- DHTrace to display the state of a DHTrace. If the DHTrace is changed on either side, it becomes Suspect. If there is no change, its state remains as Traced.
- Select any check boxes that represents the driver and Data Source to open them in the DHLink summary.
- Click
. The DHLink summary displays on the right-hand side of the dialog.
