## Purpose
This CDS view is used to extract business event header data for C2-released external events, C1-released internal events, and direct APIs.
This CDS view provides the data to answer the following business questions:
- Which business event has been logged?
To help you decide which CDS view to use for your purposes, SAP has introduced the annotation ObjectModel.supportedCapabilities that indicates the most appropriate use cases for each CDS view. To find out what use cases are best supported by this CDS view, access the entry of the CDS view in the View Browser app and find the values for this annotation under the Annotation tab. For more information, see Supported Capabilities for CDS Views.

| Field Name                | Description                                                                                                                                                                       |
|---------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| EventOperation            | Event operation, for example: Created, Deleted, Changed, and so on.                                                                                                               |
| SAPObjectType             | The object type, a business object, or a technical object corresponding to the specified SAP object node type, for example: Outbound Delivery for Outbound Delivery Item.         |
| SAPObjectNodeType         | Node type of an object type, for example, for an Outbound Delivery SAP object type, the SAP object node types are Out- bound Delivery (header) and Outbound Delivery Item (item). |
| SAPBusinessObjectNodeKey1 | First part of the key of an object node instance, for example, in one event for an Outbound Delivery Item, the first part of the key is 80013910 (outbound delivery number).      |
## Field Name
| SAPBusinessObjectNodeKey2     | Second part of the key of an object node instance, for exam- ple, in one event for an Outbound Delivery Item, the second part of the key is 00020 (item number). If an event refers to an SAP object node type with only one key part (such as: Outbound Delivery [header]), then all subsequent key parts are empty.                  |
|-------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|                               |  Note There can be many more node keys, depending on how many parts the object key has. For example: SAPBu- sinessObjectNodeKey3, SAPBusinessObjectNodeKey4, and so on. SAPObjectNodeType and SAPBusinessObjectNodeKey (1-7) identify a node instance of an SAP object. Out- bound Delivery Item is an example of an SAP object node. |

##  Note
Data conversion using the Cloud Data Integration (CDI) channel can be different from that of the other channels (ODATA, ABAP SQL Service, and so on). For example:
