SAS Lineage Window

Overview

The SAS Lineage window consists of the following components:
The Details and Filter tabs are displayed you when select an item in a diagram and click Details.

Diagram Pane

The following display shows a sample Diagram pane:
Sample All Relationships Diagram Pane
Sample All Relationships Diagram Pane
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 following display shows duplicate objects in a diagram:
Duplicate Items in a Diagram
Duplicate Objects in a 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:

Clustered Objects in a 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 toolbar at the top of the window is shown in the following display:

You can use the components in the toolbar to perform the following functions:
  • Access the Action button. The Action button duplicates many of the toolbar functions and adds the following functions: search for a subject, manage and edit views, expand and collapse diagrams, print diagrams, and import sets of relationships.
  • Select the view used in the diagram.
  • Select an object and open the pane that contains the Details and Filters tabs.
  • Display a diagram for a selected item in a new tab, This diagram uses the current view.
  • Resize the diagram.
  • Reset the zoom level.
  • Refresh the screen to display the original diagram.
The legend bar, which shows the types of connections between objects, is located at the bottom of the screen and shown in following display:
