First, I assume CCH is company code hierarchy; correct?
MDG-F uses Flex-Mode to store active data. This means that active data (ready for transactional use) is always available in the MDG active area and NOT in the application later. You ALWAYS need to replicate to the MDG system's own application layer using SOA. You can also utilize the replication model to send data to other systems.
If you want to replicate using ALE, then, you need to first replicate to the MDG system's own application layer and then configure ALE to send data to other systems.
