Creating an infoset with a symmetric difference

Symmetric difference infosets remove identical objects from two filtered infosets. The remaining data objects from both filtered infosets then combine to create a new infoset.

1. Select the infoset from which you want to remove the symmetric difference of another infoset. This infoset is the primary infoset.
   Note: Set Operations can be conducted only on user infosets, not system infosets.
   The name of the primary infoset appears within the infoset window.
2. Click Create and then click Set Ops.
3. Click Symmetric Difference and then select the infoset in which you want to find identical data objects. Data objects that are the same in the primary and selected infoset are removed, and the remaining data objects are then combined to form the new infoset.
4. Click Create Infoset.
5. Enter a name and a description for this infoset.
   When you name the infoset, avoid using commas (,). Although a comma is a valid character, it causes queries to fail when specified as part of the search text.

   If the infoset is published to the governance catalog, the description will be part of the asset details. Therefore, make it as detailed as possible.

6. Decide whether you want to create the infoset with or without the data map.
   • To generate the data map for this infoset, leave the Include Data Map for the Refine tab checkbox selected. The infoset takes longer to generate, but you can use the data map and its function later to refine the infoset.
   • To create the infoset without the data map, clear the Include Data Map for the Refine tab checkbox. In this case, the infoset generates more quickly, but no visualization of the data is available later to you for refining the infoset.
     Note: If the Compliance, Data Assessment, Data Topology, Overlay, and Customized Reports are run against an infoset without a data map, they contain no data.
7. To include this infoset in the set of objects that are synchronized with the governance catalog, select Publish to catalog.
   Even if you do not select this option, the infoset might be published to the catalog as an inferred object. This type of synchronization happens when the infoset serves as direct input to an object that is selected for publishing. The infoset is then required for proper object modeling in the governance catalog.
8. If you want specific users to be notified when the infoset is created, select Send email when the process is complete and enter the appropriate email addresses.
9. To determine the overlays that later can be applied to the infoset within the data map, click Select Overlays and add up to seven overlays.
   You can select overlays only if you select to generate the data map.
10. Click Save and View to go to the Ancestry pane, or click Save to return to the Filters pane.
