You can unassign a connection from the assigned catalog sources.
1On the Configure page, select the Lineage tab, and then select the Lineage Discovery tab.
2On the Catalog Sources panel, select the required catalog source.
You can filter the list by catalog source type or recommendations.
3Click the Assign Connections tab.
Use filters to view connections based on the connection names. Click the Add Filter menu to add filters.
4Select an assigned connection and click Unassign from the Action menu.
A warning message appears.
5Click Unassign.
A confirmation message appears. The Jobs tab of the Monitor page appears with the connection unassignment jobs. On the Assign Connections tab, click Refresh and the job status of the connection changes to Unassigning.
Note: When the job completes, the connection is successfully unassigned. The connection unassignment job updates the lineage to reference objects, but the reference objects might still appear as assigned until you re-run the catalog source job.
6If you see reference objects after the connection unassignment job completes, re-run the catalog source job to update the lineage to the pre-assignment state.
After the connections are unassigned, Metadata Command Center refreshes the percentage of matched objects versus unmatched objects in the connected catalog sources. After you re-run the catalog source job, the lineage updates to the pre-assignment state.
