Hi Saran,
MDG 7.0 provides an out-of-the-box functionality for central governance of company (T880) data. The same is refelcted by the entity type "COMPANY". In the predefined content you can find everything you need (Edition Types, CR Types) for any kind of MDG processes (Initial Load, Data Maintenance, Replication).
It is correct that you need a transport request on client side if you replicate companies. The same is valid for a couple of other entity types, too. Nevertheless, if you setup your system according to the MDG-F Configuration guide, you're on the safe side.
Best regards
Michael
