If you set the group Error Recovery property to halt a group of snapshot replications if there is an error, or an error or warning, review the replication statistics to determine the error or warning that was encountered. After you correct the problem that caused the error or warning, you can select the member of the group that caused the replications to halt and then select the Run Group from this Point command to resume replicating the group of subscriptions.
For a group of incremental subscriptions execute the Run Group command to create a baseline replication for any subscriptions in the group that have not been baselined or that have been flagged with a warning.
