Calculating Dun. Intrst After Accnts Rcvble Clearing 
You can use this function to calculate dunning charges for receivables that have already been cleared. Dunning charges that accrue interest for tax receivables are called penalty surcharges. In the SAP system, penalty surcharges are mapped by using public-law dunning interest. As the calculation of dunning interest according to receivable clearing is possible for both public-law and private-law, the following only mentions dunning interest.
The Customizing settings in Financial Accounting for the dunning procedure and the settings in Funds Management Government for dunning program enhancements are taken into consideration for the calculation of dunning charges.
The system calculates the dunning charges that have been incurred between the last dunning run and the clearing of open items. The system also checks whether any dunning interest already incurred has been correctly calculated, that means, for example, whether backdated part payments were taken into consideration when the dunning interest was calculated.
For the public-law dunning procedure, you can define a grace period in the Customizing of Funds Management Government . This enables you to define that the payment was received within the specified grace period for each payment type (for example, cash payment or transfer). The program evaluates this grace period when calculating public-law dunning charges after the receivable clearing.
Example
You have a tax receivable that is due on 10.01. On 01.02. you carry out a dunning run and send a reminder of the receivable to the debtor. The debtor pays the open receivable on 18.02. The next dunning run on 01.03. does not take this account receivable into account, as it has been settled in the meantime.
For the period between the due date (10.01.) and payment (18.02.) of the account receivable, the debtor must pay a penalty surcharge. The dunning run on 01.02. calculates the penalty surcharge for the period from 10.01. to 09.02. In the next dunning run on 01.03. no penalty surcharge is calculated, as the receivable has been paid in the meantime. However, the debtor must pay a penalty surcharge for the period from 10.02. to 18.02., as another penalty month has begun. This penalty surcharge can be calculated using this function.
When you execute this function, no dunning run (in the true sense) takes place, as the program only takes cleared items into consideration and does not generate any dunning administration data. The dunning level of the items is not increased either.
The system outputs a log listing the customers and clearing documents that have been processed and the document numbers of posted interest.
Note
If this program should exclude clearing documents from the interest calculation, you can program event "00103015" with the help of Business Transaction Event.
You must have set indicator Dunning interests should be posted in Funds Management Government Customizing, step Enhance dunning procedure .
You must also have defined the document type and revenue type that are to be used for the automatic posting.
You find this function in the Funds Management menu under
