After having created the Consumption Model (see Creating the Consumption Model) you now need to add the Data Model(s) to the Consumption Model. If you created a UC Data Model, you need to add this too.
In the navigation tree in the Object Navigator select Consumption Model ZSFLIGHT02_0001.
Right-click the Consumption Model and choose Add SAP GW Data Model from the context menu.
In the Add Data Model window enter the model identifier ZSFLIGHT02_0001_PS or search for a Data Model via the input help. Then choose Continue (Enter).
Optionally, repeat step 3 to add the UC Data Model ZSFLIGHT02_0001_UC.
The Data Model has been added to the Consumption Model and is displayed in the navigation tree in the Object Navigator.
Proceed with checking the service.
