ArcGIS Pipeline Referencing supports two event registration types: registration of events in the LRS geodatabase and registration of events stored in an external database. Events stored in the LRS geodatabase are stored as feature classes, while external events can be configured with or without a connection file. With a connection file, the external events are linked to tables or feature classes in an external relational database management system (RDBMS) and stored as feature classes in the LRS geodatabase. Without a connection file, the external events are created directly in the LRS geodatabase.
External events with a connection file
You can use the Configure External Event With LRS tool to connect to and register event data that is stored and maintained outside the LRS geodatabase. This is important because some event data is traditionally considered to be nonspatial tabular data.
The LRS allows you to set up a read-only connection to external event data sources and use them to visualize tabular data in a spatial way and to spatially integrate your business data with other enterprise data.
Tip:
You can right-click an external event data source in the LRS Hierarchy pane and add it to a map or scene in ArcGIS Pro.

The following are data requirements and recommendations for registering an external event with the LRS:
- Must have an event ID and route ID
- The From Route ID and To Route ID fields are required for events that span routes.
- The event ID field in external business tables or feature classes must be a text field.
- Globally unique identifiers (GUID) are read as text.
- Can have a datetime field
- The SQL Server datetime2 data type is not supported; use the datetime data type.
- If no datetime field is used, full temporal viewing of event data is not supported.
- A single effective date can be used, but it is recommended that you include both start and end dates.
- Point events require only one measure field; linear events require two measure fields.
ArcGIS Pipeline Referencing supports pushing updates to the external system through web services.

External events without a connection file
The Configure External Event Behaviors With LRS tool allows you to create external events without linking to a source table or feature. This works for scenarios such as when there is limited access to the event data, or when the event data is not stored as tables in an RDBMS or as feature classes in a geodatabase.
This type of external event is not a feature class, but ArcGIS Pipeline Referencing still supports updating and maintaining external events through web services.
Tip:
You can right-click an external event data source in the LRS Hierarchy pane to review its properties. However, this type of external event cannot be added to a map or scene in ArcGIS Pro.
You do not need route or event information to configure external events that do not have a connection file. To update external events, provide required route and event information in the web service.
