What causes this issue?

You wish to switch from a data model to the assigned object type.
However, this is not possible because no object type is assigned to
this data model.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Please check whether you are in the required data model.
If necessary, assign this data model an object type. For this, switch
to the change mode and go back to the object type. You reach the
Business Object Repository and can create the object there. The object
is created under the data model name and the short description of the
data model is transferred automatically.
However, you can also exit the Data Modeler and start the Business
Object Repository. Switch to the change mode for the object types.
There select the appropriate object type, then switch to process basic
data and there create the name of the current data model in the field
BO data model.
