How to set any default values or to set any validation or derivation rule from BRF+

Hi Experts,

      1.   I am trying to set a default initial value in some required fields in NWBC using BRF+.

            Can anyone please  help me to know the exact step to achieve that.I have wriiten some derivation rules but it is not reflecting in the nwbc ui screen.

      2 .  I have tried to set some business rules for field level validation from BRF+,and I have written some rules in BRF+ and when I test those rules from BRF+ start simulation, the rules were executed  properly but those field level validation was not reflecting in the NWBC screens when I am tring to create a new CR.

    Please suggest me on how to reflect those rules,field level validations in NWBC.
