The business transaction ‘Changes in Interest Rates’ is provided for changes in the interest rate for an existing deal. This causes a change in the loan instalments while retaining the term for the deal. If the interest rate increases, the instalments increase whereas if the interest rate decreases, the instalments decrease. The next due date for payment, which is the date for changing the interest rate agreement and the annuity, is determined on the basis of the current posting date and the payment frequency.

After the data have been entered, the change to the deal is shown by clicking on "Execute” and confirming by clicking on
