The aim of combining trading periods with accounting periods is to make the system automatically close a trading period if an accounting period is closed. Accounting periods are treated with a higher priority as compared to trading periods. Nevertheless, because of the separation of these periods, it is possible to close a trading period not closing an accounting period automatically.

When adding a new trading period, it is first necessary to add a new accounting period.

If the system finds an open accounting period, it “associates” it with a new trading period being created. In the trading period’s definition, the date From is set by default as:

• The first day of a current month – if this date falls within the open accounting period
• The first “free” date falling within the accounting period – if the first day of a current month is covered by a confirmed accounting period
