I also had a similar question. What we would like to do is when someone logs a defect - they would select the 'Requirement' it applies to from the requirements listed (Name) and then based on the rqmt selected, it would take the 'owner' of that requirement and populate the 'assignee' field in the defect being logged.
so first we would have to be able to view the requirements from the defects module (in list form) and then once you make a selection, defect module would 'auto populate' assignee field based on 'owner' of requirement.
Does that make sense or is there a better way to do it?
