I have a questions around reverse replication into MDG HUB .
We have MDG HUB running on S/4 instance and we have ECC as a target system . Customer contact person is updated /created or deleted on MDG HUB by a Business user OR Customer contact person can be updated , created or deleted in our ECC instances via external interfaces Proxy call .
We are trying to design a solution where customer contact person can have two source - MDG HUB and ECC . if in ECC , how do we reverse ALE to MDG HUB ? Does SAP MDG have any out of the box replication method for changes to specific fields to be sent to MDG HUB ?
Contact Person created in MDG -----> ECC
Contact Person created in ECC -------> MDG ( avoid any snapshot issue with existing CR)
I am sure with MDG as SAP MDM soultion this feature should be available . Please advise .
