Dunning by dunning procedure determines the number of dunning levels and the respective dunning activity sequence depending on the days in arrears and the amount of debt.
Dunning by collection strategy is based on business rules that are evaluated at run-time. This allows for a flexible evaluation of a broad range of parameters. The evaluation of the business rules within the strategy return the next collection step and related activities to be carried out. There's not necessarily a fixed sequence of steps to be carried out one after the other. It's the specific circumstance of an account that determines the next collection step. The data that can be evaluated in the rules engine includes dunning data, dunning history, credit risk data, and much more (including customer-specific tables).
