We've installed the backend as described and I'm getting the error mentioned below. pyodbc is installed and I've added django_hana_odbc in the installed applicatoins in settings.py. Please advise. thanks:

django.core.exceptions.ImproperlyConfigured: 'django_hana_odbc' isn't an available database backend.
Try using 'django.db.backends.XXX', where XXX is one of:
