Enhancement Point FOR CO11 is Required

I am trying to update some custome fields in AFKO table. As per requirement we need to update these fileds only once the production order is confirmed. I am using CONFPP05 and user exit EXIT_SAPLCORF_105. But found that when program control come to this point , order is not yet confirmed and there is no data in JEST table. So now I need some enhancement point which will get trigger just after the confirmation commit process. Please suggest.
