In the planned interest calculation, the system always uses the totals records to reproduce the balance carried forward for costs and revenues.
Depending on the settings entered in Customizing, the balance carried forward is made up of either totals records or line items. If you opted to allow planned line items to be written (by assigning a number range to transaction FIPA in the IMG), the planned interest calculation takes place to the day, based on plan line items. If the line item update is not active, the planned interest calculation uses totals records.
