SAP Replication Server translates commands from the primary database into SAP Replication Server functions that represent data server operations such as insert, delete, select, begin transaction, and so on. It distributes these functions to remote SAP Replication Servers in the system, where they execute those operations in remote databases.
See Customize Database Operations in the Administration Guide Volume 2 to customizing function strings for system functions.
The system functions described may have function-string- class scope or replication-definition scope.
A function that has function-string class scope is defined once, for its class. It is then applied the same way in every database to which the class is assigned.
A function that has replication definition scope is defined once for each replication definition. It is then applied the same way for every operation (update, insert, and so on) that is replicated using the replication definition.
