wf_local_synch.propagate_user API not updating data in WF_LOCAL_ROLES

Hi Experts,

Customer has raised a requirement to update the data in WF_LOCAL_ROLES.

For example if we want update the notification preference for employee, Using the following piece of code to verify the same

declare

  l_attributes wf_parameter_list_t;

begin

 

  wf_event.addparametertolist('orclWorkFlowNotificationPref','MAILHTML',l_attributes);

  wf_local_synch.propagate_user(p_orig_system     => 'HZ_PARTY',

                                p_orig_system_id  => 2443,

                                p_attributes      => l_attributes,

                                p_start_date      => null,

                                p_expiration_date => null);

commit;

end;

But I have observed that this API has not updated the data in WF_LOCAL_ROLES data.

Any inputs would be truly appreciated.
