If you use a class that does not inherit from a system-provided class, you must create all function strings yourself, and add new function strings whenever you create a new table or function replication definition.
Use the create function string class command to create a new function-string class, and then create function strings for all of the functions with function-string-class scope.
You must create rs_insert, rs_update, and rs_delete function strings for each table you replicate in the database.
If you are replicating columns with text or image datatypes, you must create rs_datarow_for_writetext, rs_get_textptr, rs_textptr_init, and rs_writetext function strings for each text or image column. The function-string name must be the text or image column name for the replication definition.
The rs_select and rs_select_with_lock function strings are needed only if the database has the primary data for a replication definition.
