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 a 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.
