A levelled recurring journal requires the allocation of a time allocation key used to set up a payment schedule, as well as various weighings from one month to another (see the Time allocation documentation).

SEEWARNING It is important to check the consistency of this key with the frequency and the date ranges previously defined.

If the date ranges do not include the allocation key in its entirety, the amount of the open items will be calculated in proportion to the rates of the period defined by these ranges.

For instance: An allocation key determines that in January, 50% of the total amount will be settled, in June, 20% and in Decembrer 30%. For a total amount of 1000, the recurring journal over one year should give rise to three open items: 500, 200 and 300. If the date ranges reduce the period from January to May, the whole amount will be settled in January (50%/50%Þ 100%)

The same principle applies in the case of an inconsistency between the frequency and the allocation key.
