Item interest calculation in SAP

This documents explains the customization and how system calculate interest when we select the check box Open and all cleared items and open items and items cleared with a payment.

Intoduction:

Every company has their own pre-defined policies/terms and conditions towards the collection of the debts from the customers. These policies/terms and conditions depend upon the legal environment that exist in the countries where the company carries on its operations. One of the prominent policy/terms and condition would be to have an interest clause in the sales invoice to levy interest on the receivables.

The purpose of this document is to communicate to the readers the process of charging such interest on the receivables to the customers and posting an accounting document on the customer accounts.

The process followed for calculating the interest calculation on customer accounts would be to execute the interest calculation run for a defined period for defined accounts. The system would calculate the interest based on the customization maintained related to interest indicators. The calculation run can be executed further to post an interest document in the customer accounts. For correspondence with the customers, the same run can generate an output document (like invoice) which contain the amount of interest charged and the receivables towards which such interest is charged.

Interest can be calculated on customer and vendor accounts in two ways:

Account balance interest calculation: This calculation type calculates interest on the balance of the customer on the interest calculation day. If the customer has a debit balance (receivable) then the debit interest rate will be taken into consideration and if the customer has a credit balance then the credit interest rate will be considered for calculation.Account balance

Item interest calculation: This calculation type calculates interest on the line items for a customer. A customer may have open line item as well as cleared line items. Interest can be calculated for both open and cleared line items or only on the open line item.

Customization Transaction Code and Path given below

1. Interest calculation customization done at client level
2. Assigning interest calculation to customer master data at company code level

The below Setting done in transaction code OB82

Selected interest term with Open and all cleared items.

Once all the customization comleted assig at customer master data .

Same interest indicator we use at dunning customization :

At dunning this indicator only becomes effective if there is no interest calculation indicator entered in the master record. Otherwise the indicator in the master record has priority. If there is no indicator at either level (dunning procedure or master record), i.e. 'BLANK' is entered, then no dunning interest is calculated by the system
