If the requirement is to selectively display group box in case a particular condition is true or in case for a particular employee or role, you can display the group box by the below code:
if ASGN_VW.EMPLID = "101" Then DERIVED_HR.AB_PLAN_GRPBOX.Visible = False; Else DERIVED_HR.AB_PLAN_GRPBOX.Visible = True; End-If;
