User-defined class has the name of a class inside the ESRI Classes package (reserved)

Error Message

The ESRI Semantics Checker returns the following error:

"User-defined class has the name of a class inside the ESRI Classes package (reserved)."

Cause

Note:
User-defined classes should exist below the Workspace package.

Solution or Workaround

1. Right-click on Logical View in the Model Explorer.
2. Select Properties.
3. Select Package under Categories.
4. Select the empty line in the Stereotype drop-down menu.
5. Click OK.
