Built-in Services for Echo Suppression
Adding Echo Suppression to Notification Services
Adding Echo Suppression to Update Trigger Services
When you use n-way synchronization, you need to include logic that performs echo suppression to the:
*Notification services that run on source Integration Servers. For a description of notification services, see Setting Up Key Cross-Referencing in the Source Integration Server .
*Update services that run on target Integration Servers. For a description of update services, see Setting Up Key Cross-Referencing in the Target Integration Server .
Echo suppression logic blocks circular updating of data changes from occurring. Echo suppression is not needed when you use one-way synchronization.
Note:
For an overview of echo suppression, including information about how echo suppression solves the problem of circular updating, see Echo Suppression for N-Way Synchronizations.
