Several new system tables have been added to Replication Server 15.7 in place of rs_functions .
See Reference Manual > Replication Server System Functions > rs_clsfunctions.
See Reference Manual > Replication Server System Functions > rs_objfunctions.
See Reference Manual > Replication Server System Functions > rs_asyncfuncs.
In versions of Replication Server earlier than 15.7, rs_functions stored information about class-wide and object-wide functions, which are cached by funcname. As many replication definitions share the same function name, such as rs_insert, rs_update, and rs_delete, the rows for object-wide functions should not be cached by funcname. In version 15.7 and later, the rows in rs_functions are split into two categories and stored in rs_clsfunctions and rs_objfunctions.
In version 15.7 and later, rs_functions is no longer a table. To support Replication Server backward compatibility, rs_functions is maintained as a view from the union of rs_clsfunctions and rs_objfunctions.
