Description
With program RFFMINTCALC, you can calculate dunning interest orpenalty surchares for receivables already cleared taking into accountthe Customizing settings for dunning procedure in FI and theenhanncements of the dunning program in IS-PS.
You use this program to calculate dunning interest amounts that occurredbetween the last dunning run and the clearing of open items.
When executing the program, no dunning run is executed in the true senseof the word as the program only takes cleared items into account anddoes not generate any dunning management data. Dunning level increasesof item do also not take place.
If you start the program in the test run, you can display which dunninginterest was posted. An update only takes place in the real run.

Selection of documents
All clearing documents from the clearing date entered are selected thatmatch the selection criteria for company codes and customers.
Note:
SAP delivers the BTE event '00103015' which you can use to excludeclearing documents from interest calculation. For information of thefunctions of Business Transaction Events, seeBTE.

Calculating Dunning Interest
The interest of the cleared items are calculated subsequently for eachclearing document by a fixed end date. This end date is set for eachclearing document on the newest due date that occurs in the clearingdocuments. However, if the clearing date is older than the set due date,the clearing date is set as the end date.
If you want to set a different date for the end of the interestcalculation, you can override the date usingBTE event '00103010'. You might want to dothis if a tolerance should be included in accordance with the incomingpayment (for example, by check).
The interest is calculated depending on the dunning procedure(public-law procedure: started month, private-law procedure : days) forthe entire period analog to the dunning program. The difference betweenthe dunning interest that already exists and the newly calculateddunning interest is formed. If this difference is above the lowestamount defined in the Customizing of the dunning procedure, thecalculated difference is updated in the update run.

Restrictions
It is not possible to calculate dunning interest if

• Documents with a dunning block are included in a clearing document


• Documents with a different dunning procedure are grouped together in one
clearing document

• Documents were transferred to an external execution procedure. In this
case, it is assumed that the interest can be calculated correctly in theexecution procedure:
In addition to this, note the following:

• The dunning level of the items is not changed


• Dunning charges are not calculated as no dunning form is printed


• Interest or charges are not calculated


• The posting date for the incoming payment to the bank (value date) is
not included in the calculation of the end date. You should thereforeset the same document date and value date of the incoming payment.

Authorizations
The program checks the same authorizations as when printing a dunningprintout (test printout or real printout) with the standard dunningprogram.


• Dunning interest is only updated automatically if the indicator
Dunning Interest Should be Posted in IMG activityEnhance Dunning Procedure in the Customizing ofFunds Managements Government. You must also define the documenttype and the revenue type that should be used for automatic updates.

• You should start the program in the

Example
Calculation of end date for interest calculation
Document,,Document date,,Due date,, Amount
Invoice 1,,01.01.2000,,15.01.2000,, 450,00 euro
Partial payment ,,01.03.2000,,01.03.2000,, 200,00 euro
Invoice 2,,01.04.2000,,30.04.2000,, 250,00 euro
Payment,, 10.04.2000,,10.04.2000,, 500,00 euro
Clearing date: 10.04.2000
The end date is set to 30.04.2000 (newest due date). As the clearing wasalready carried out on 10.04.2000, the end date is set to 10.04.2000.
If you grant a tolerance, for example of 5 days, you can set the date to05.04.2000. As a result, the dunning interest would be calculated by05.04.2000.
