The dunning procedure is the driver for dunning.
You can define different dunning levels for each dunning procedure to determine the dunning frequency, and the calculation and posting of charges and interests.
You can define minimum amounts and dunning activities for each dunning level.
You can define minimum interest due for each dunning level so that it is posted.
You can allocate a dunning procedure to contract accounts or for each individual line item.
IMG: Transaction SPRO.
Financial Accounting (New) → Contract Accounts Receivable and Payable → Business Transactions → Dunning → Dunning by Dunning Procedure → Configure Dunning Procedure.
Select Dunning Procedure 01, and double-click on Dunning level in the dialog structure on the left-hand side.
Double-click Entry 1 in the dunning level overview.

The dunning frequency is the minimum number of days that must have expired since the issue date of the last dunning notice.
The charge schedule is used to determine the charges that are usually levied in connection with the creation of dunning notices and other correspondence.
You can select Always Dun to trigger a dunning notice at this dunning level as soon as the dunning frequency is reached in the dunning program, regardless of whether the days in arrears or minimum amounts have been reached.
You can select Print All Items to list all items that fulfill the same criteria for dunning grouping in the dunning notice, regardless of whether they're due.
You can select Interest before Charges to make the calculation of dunning charges dependent on whether interest has been calculated for items due for dunning. Usually, interest in the dunning activity run is calculated and posted in accordance with the charges.
You can use function module FKK_SPECIALCHARGE_0360 to restrict the amount of the dunning charge if dunning interest is also to be charged alongside the dunning charge (penalty charges).

The dunning activities that were carried out are recorded in an application log.
You can specify an activity to deactivate an installment plan.
After the installment plan has been deactivated, the source receivables are dunned again.
You can specify an activity to start a workflow to trigger an agent notification.
You can specify an activity to request a cash security deposit (industry solutions).
You can specify an activity to create a disconnection document (industry solutions).
You can specify an activity to release receivables for submission to a collection agency.
You can specify an activity to set a dunning lock for the dunned contract account.
You can enter default values for the duration of a lock in customizing.
Customizing: Financial Accounting (New) → Contract Accounts Receivable and Payable → Business Transactions → Dunning → Configure Dunning Activities.

You can assign any number of dunning activities to various dunning levels.
The dunning activity configuration consists of a function module and an application form.
The application form can be modeled in the print workbench (transaction EFRM).
The application form is needed if the dunning activity creates a dunning notice.
The sample function module contains the string _0350 and starts with FKK_:
FSC_SAMPLE_0350_CCC
Print dunning notice
FKK_SAMPLE_0350_SBHINWEIS
Send note to agent using SAP Office
FKK_COLL_AGENCY_RELEASE_0350
Release items for submission to collection agency
FKK_RECALL_FROM_AGENCY_0350
Recall of submitted items from collection agency
FSC_DUNNING_DEACT_INSTPL_0350
Deactivate installment plan
FKK_WLI_CREATE_AND_CLOSE_0350
Workflow for reminder call

The charge schedule can manage charge data for a maximum of three charge categories:
- Dunning charges
- Payment charges
- Postage charges
The charge schedule can manage industry-specific charges (disconnection, reconnection, or administration charges) and customer-specific charges as well.
The charge schedule can be assigned to correspondence types of a correspondence variant. When these correspondences are created, the system automatically posts the charges defined in the charge schedule.
For the charge category, the main transaction and subtransaction with which the charge is to be posted is determined (real or statistical posting).
For each combination of a charge schedule and a charge category, you can determine how charges are to be calculated depending on the currency, the dunning balance, and creditworthiness.
