# Manage data lineage

# Manage data lineage {#ariaid-title1}

Data lineage is the visual representation of the relationships you define in a hierarchy. You can add new relationships directly from the lineage map in a processing map.

Every hierarchy relationship you create for a processing activity is rendered as a lineage map. An analyst can add relationships directly on the processing activity, and a business user can define relationships through a privacy
impact assessment (PIA). The map lets you trace how data flows between vendors, applications, systems, and other processing activities from a source record. This helps you identify where privacy-related risks exist. For more on
data lineages, see [View lineage map](https://www.servicenow.com/docs/59ahVt9bV2eqlUFLaG9Owg#hierarchy-tab__section_lineage_map).

For a lineage map to be created, you must first create a hierarchy relationship. For steps, see [Add relationships to a hierarchy for a processing activity](https://www.servicenow.com/docs/weJyMBCNVAnBbk~o3VoENw "Define new relationships in a hierarchy directly on a processing activity to record how it connects to vendors, applications, systems, and other processing activities across regions. This enables you to track cross-border data transfers and generate a lineage map to visualize data consumption, sharing, and the associated risks for a processing activity.").

Use the following tasks to manage the lineage map for a processing activity:

* [Edit a lineage](https://www.servicenow.com/docs/ISr3HJokLHh1mRcpoESPYw "Edit an existing lineage relationship to update the relationship type, description, or key relationship status of a connected node.")
* [Delete a lineage](https://www.servicenow.com/docs/E0X8mlISevUokK7TuiA0aQ "Delete a lineage to remove a specific connection or node from the hierarchy of a processing activity.")
* [Update the maximum node level for the lineage map](https://www.servicenow.com/docs/06oiT2NI7TCl1URSbrPiYA "Update the sn_privacy.nodemap.maxLevel system property to control how many node levels are visible on the lineage map.")
