If you are having problems with customized function strings, which can be used to replicate changes, you might have used incorrect variables. Here are the restrictions:
Pre-11.0.2 release Replication Server function strings can use system-defined variables. Function-string class scope functions cannot use the defaults.
Only function strings for rs_insert and rs_update can use new column values.
Only function strings for rs_delete and rs_update can use old column values.
Only function strings for rs_select and rs_select_with_lock can have input templates. Only they can use user-defined variables.
Only function strings for user-defined functions can use parameter values of functions. The parameter value of a function consists of the parameters passed to a replicated stored procedure.
