Description
When synchronizing a replica, the workspaces containing the replicas must be in a consistent state. If there are pending edits in the workspace, replicas can become out of sync after the synchronization process. For example, if a replica is synchronized with pending edits and those edits are subsequently discarded, the discarded edits are not transferred to the relative replica in the next synchronization. For this reason, save or discard your pending edits in Geodatabase 1 before synchronizing a replica.
Solution
Save or discard pending edits in Geodatabase 1 before synchronizing a replica.
