Shilpa:
I would question whether the design here is capable of achieving your desired results. You cannot really combine brf (plus or not) with dunning procedure approach within dunning. I would expect challenges as you are experiencing since the dunning procedure still wants a linear procession while brf wants to avoid linearity. For the most part your brf rules would have to follow the same path already decided by the procedure.
Why would this design be used?
