This allows you to set the appropriate standing order prefix in an account item by selecting from a list of payment repetition intervals. You can also use the list to change or remove an existing S/o prefix.
By selecting a repetition interval, the account item will be repeated automatically as each due date comes around.
You can also specify whether the standing order is to repeat indefinitely or until an end date you specify. Just check the limiting date box and set the last date on which the standing order is to be paid.
Note that the default date is set one year ahead.
In fact the new items are created on the first day of the month in which they occur so that you can see the automatic payments and receipts in the month ahead. It helps your cash flow planning.
