Forecast entries look like accounting entries, but they refer to future transactions, like for example the monthly rate of quotas that are usually posted at the end of the year.
Forecast entries can also be used to post documents to be issued and to be received, in order to create the payment schedule in advance or only to get a simulation of the VAT settlement.
When forecast entries are no longer temporary entries, proper procedures transform them into actual accounting entries, releasing the accountant from repeating the posting of all data in the actual accounting.
