Prism Users Guide - Chapter 31. Centrals
31.9 Replication of Centrals Information

Preferences
The preference defined in Node Preferences > Transactions > Centrals are replicated throughout the enterprise. Care must be taken to set these preferences at the desired level and then avoid overwriting the settings at lower-level nodes.
The Centrals server settings defined in Installation Defaults are not replicated; they must be entered on each machine running centrals.

Central Credit Balances
A customer's central credit (updated) balance is replicated as part of the customer record to any other station set up for replication. However, even though central credit balance is visible when looking up a customer in the Customer module (in the ‘Payments' tab), that balance is not useable for transactions if the Prism server is not set up to use Centrals functionality.
