# Description
This PR fixes today's issue on dbt test, since we had a duplicated booking in this table.
Technically, according to Daga, a booking can only be overridden with a new program ONLY if the first program was the default BasicScreening, and it's a new bundle containing a Paid Service. Once there's a product bundle applied to a booking that contains a paid service, it cannot be overridden.
Thus in essence, by just keeping the latest update date it will only take into account the potential switch to a paid service, that is what really matters, and cannot change afterwards.
