# Context Service

Track changes to your context definitions with Setup Audit Trail for create, update, and delete actions across context definitions, nodes, attributes, mappings, and filters. Context Service resolves parent-child relationships between data model objects (DMOs) in Data 360 and returns complete multilevel data hierarchies in a single hydration call. This includes zero-copy DMOs backed by external warehouses.

- **[Track Changes to Context Definitions with Setup Audit Trail](https://help.salesforce.com/s/articleView?id=release-notes.rn_ctx_setup_audit_trail.htm&release=264.0.0&type=5)**  
    Gain visibility into how your context definitions are modified over time. Setup Audit Trail now captures create, update, and delete actions across context definitions and their related configurations, including context nodes, attributes, tags, mappings, and filters. Setup Audit Trail also captures create and delete actions of transforms in Context Service. Review audit logs to troubleshoot configuration issues and meet governance requirements with documented change history retained for 180 days.
- **[Hydrate Complete Data 360 Hierarchies in Context Service](https://help.salesforce.com/s/articleView?id=release-notes.rn_ctx_hydrate_data_cloud_hierarchies.htm&release=264.0.0&type=5)**  
    Context Service resolves parent-child relationships between data model objects (DMOs) in Data 360 and returns complete multilevel data hierarchies in a single hydration call. When you configure a DMO hierarchy, such as member demographics, health plan enrollment, or claims history, Context Service identifies the join fields from Data 360's relationship metadata. Previously, AI agents, recommendation engines, and automations that relied on context definitions received incomplete profiles because child DMO data was unavailable.
