Creating Client Data Objects
Client data objects are client-side projections of data objects defined in the Data Orchestration Engine (DOE). Service operations are defined on top of the client data objects and cannot access the DOE data objects directly. Using the Object Editor, you can define attributes, relations, and indices.
You have created a development component and defined its dependencies.

1. In the Service Explorer, open the Data Objects context menu and select Import Data Objects.
2. In the Create Data Objects wizard, select the DOE instance from which you want to import.
3. Select the data objects to import.

The option ABAP names uses the same names for nodes and attributes as are maintained in the middleware. The option Java names derives Java-conform names from the ABAP names for the sake of consistency in the Java development environment.
4. Select the desired nodes and attributes.
The wizard shows a list of all available data objects and their attributes. Data objects, which are already used, are dimmed, since they cannot be imported here, but only be reimported.

The client data objects have been created and appear under the Data Objects node in the Service Explorer.
