SAS Lineage Window

The Details and Filter tabs are displayed you when select an item in a diagram and click Details.

The Diagram pane displays the diagram for the object that you selected in the Select a Lineage Subject window. The pane will be empty if you closed the Select a Lineage Subject window without selecting a subject. See Selecting a Subject.

The pane shows the selected subject in the default view. For information about changing the default view, see Manage User-Defined Views.

Due to how relationships work, diagrams can include duplicate objects, such as the same job, as a source and a target. These duplicate objects are displayed in only the Impact Analysis and Governance diagrams. They are not displayed in All Relationships diagrams.

An example of a diagram that displays duplicates is a transformation that can both read from and write to the same table. Objects representing the table appear both upstream from the transformation node and downstream from the transformation node in the diagram.

The duplicate objects are identified by an icon in the lower right corner of the node. The only special action associated with duplicate objects is that selecting one of the duplicate objects in the diagram causes its matching node to be also selected.

Objects can also be clustered in the diagram. Objects are clustered based on their types, relationship to the expanded object, and direction of that relationship. If enough objects of the same type are related to the expanded object with the same relationship type and relationship direction, these objects are clustered together as one node in the diagram. The following diagram shows a partially expanded cluster of objects in diagram:

When a clustered object is expanded, it displays all of the relationships that its member objects are a part of, except relationships between member objects. Expanding a clustered object is similar to having expanded each member object individually. Once a clustered object has been expanded, when any of its members are unclustered, those objects should be added to the diagram in a fully expanded state. If a clustered object has not been expanded, any member objects that are added to the diagram are displayed in a collapsed state, unless all of the objects to which that member object is related are already present on the diagram.

The pane that contains the Details tab and the Filter tab are displayed when you select an object in a diagram and click Details.

The Open link button is also available in the Details tab to enable you to access the selected item in a linked application.

You can create filter conditions and apply them to the current diagram. You can use the Action button to save the filter conditions as a view and add it to View menu. For more information about filters, see Create a User-Defined View.
