How do I check the replication schedule to determine when it will start and when it will completes?
A replication schedule will start a replication based on the schedule you have defined.
It will complete once it has finished transferring the data in a dataset.
You can check the properties of the replication link in the remote replication section of the Web Manager which will show the status of any currently running or completed transfers.
