FAQ: What are the SYNC_SEND and SYNC_RECEIVE versions in the versions table?
What are the SYNC_SEND and SYNC_RECEIVE versions in the versions table?
In geodatabase replication, on a successful synchronization between parent and child replicas, SYNC_RECEIVE and SYNC_SEND versions are recorded in the sde versions table. These temporary versions are managed by ArcSDE and should not be manually deleted from the table. They are deleted when the replica is unregistered by way of the Replica Manager dialog box in ArcCatalog or ArcMap.
