How to fix this error?

When you insert an entity type, only the following options are
provided:
1. Create a new entity type (with or without assignment to a data
model)
2. Assign an existing entity type to a data model
The entity type that was entered already exists, but was not placed on
a data model (colored-in area) when it was created graphically.
The insertion process is, therefore, canceled.
