Transaction Replication

  • Finished transactions are replicated to the central server, to SDC or to POS Server or via Store Hub.
  • For this operation, the POS Client must be online.
  • Transactions that were finished when the POS Client was offline are replicated when the POS Client is online again (blackout scenario - see Master Sizing Guide).
