By default, when a checkout replica is created it is tagged with the owner ID. Because of this you will get a "Synchronize Replica Failed - Version Not Found" error if anyone but the owner tries to synchronized the replica.
I need to allow others to do the synchronization of replicas in my absence.
Is there a way to do this?
A synchronization involves one replica sending data changes and the relative replica receiving changes. Data changes include inserts, updates, and deletes made in the replica version. To perform a synchronization, you must be connected as the same database user as that used to create the replica, or the geodatabase administrator.
