Follow up action duriing usage decision

I have done the necessary configurations for triggering followup actions after doing usage decision in the system like

1. defined follow up configuration and assigned functional module to it
2. defined codes and code groups in qs41
3. defined selected sets with follow up actions in qs51

and I would like to know why after these settings are made the followup action is not  getting triggered in the field followup actionwhile doing UD  after  providing valuation code .

Is there any others settings i need to make after these is so please help me in getting this triggered

Thanks in advance......
