When creating an account via the UI, a dunning group is automatically created for each Master Plan Instance assigned on the account. This way, Master Plan Instances associated with the same account dun separately (i.e. once an Master Plan Instance goes into dunning, it will not affect anything else). You may want to combine two or more Master Plan Instances into a single dunning group to coordinate the final step in dunning.
All active dunning groups are displayed and can be managed from the Dunning Groups screen, detailed below.
