An additional receivable is a receivable that is caused by another receivable, such as dunning charges or interests. In several cases, these additional receivables should not be dunned or have interest calculated for them independently.
Interest can be calculated for an item that is not marked as an additional receivable in the transaction attributes and a dunning notice issued if no blocks are set.

The dunning procedure is made up of individual dunning levels. You enter various information for each dunning level, such as the minimum amount of an overdue item and the number of days in arrears that must be reached before the item is placed in the next dunning level.
The most common dunning activity is creating a dunning notice. Other examples include posting interest and charges, processing a note for an agent, or starting a workflow.
The dunning level indicates how often this item has already been included in a dunning run.
The highest dunning level reached by any of the items determines the dunning activities.
The dunning level of an item can also be decreased by the dunning program if, on the basis of the amount limits, the item would no longer reach this level (after a partial payment).
The dunning procedure and collection strategy are the basic solutions of dunning in FI-CA. They have to be activated in the FI-CA company code settings.
