Introduction to Interest Calculation

When you calculate interest on G/L accounts, a graduated list is produced. You can also have the balance interest calculation run logged by the system. This is especially useful if the run does not produce the result you expected. By checking the log, you can find out why interest was not calculated for a certain account.

The balance interest calculation program is controlled using the following specifications:

data from the G/L account master record. This includes, for example, the interest indicator which the report uses and data used for determining the interest calculation period for the account.
Specifications stored in the interest indicator. These include, among other things, the interest rates to be used.
Specifications made for the balance interest calculation run, such as selection criteria which limit the accounts to be included in the run.

The following topic deals with those fields in a G/L account master record which are relevant for balance interest calculation. The topics after it explain how the interest indicator works and how the interest calculation period for the balance interest calculation run is determined. You may have to modify the interest rates defined in the system before running the balance interest calculation program. For more information on this, see Modifying Interest Rates.

The last topic in this section describes how to carry out a balance interest calculation run and how you can control this procedure.
