Case 1: Destination content type has to be ignored
Assume you have a source endpoint with a content type: Destination and a destination endpoint with a content type: Destination. But each Content Type is manually input and manually maintained. You need to sync the content type to store a field value from the source content into a variable. Or you need to sync the content to populate the id-maps. But you don't want to sync the content type: Destination from the source endpoint to the destination endpoint.
