Given an ODS and a copy of LUCIDERA_ANALYTICS in the repository, the following query returns only the ODS app (but should return both):

select v
from class ModelElement where name in ('WAREHOUSE_SCHEMA','ODS_VARS') then (
    recursively (
        follow composite backward
    )
) gather with parent then (
        follow composite backward destination class AppTemplate as v
);

The query below returns the correct results:

select v
from class ModelElement where name in ('WAREHOUSE_SCHEMA','ODS_VARS') then (
    recursively (
        follow association ElementOwnership backward
    )
) gather with parent then (
        follow association ElementOwnership backward destination class AppTemplate as v
);
