Non-Calendar Fiscal Years 
Non-Calendar Fiscal Years
Use
If you choose to work with a non-calendar fiscal year, you need a General Ledger fiscal year variant with posting periods defined for it (FI-Customizing: Financial Accounting Global Settings). Assign this fiscal year version to the global company code parameters.
Features
Using a non-calendar fiscal year does not require special system settings in Asset Accounting. You make all date entries (such as the posting date) as normal calendar dates.
Once assets have been posted, you can no longer change the fiscal year variant of a company code in the current fiscal year, unless there was no posting in any changed period.
Calendar Assignments in Period Control
When you assign the company code to a chart of depreciation, the system automatically (one time only) makes the calendar assignments for a non-calendar fiscal year for the standard period control in Asset Accounting (for example, first-year convention of a half year). In order for this to occur, you need to have defined the fiscal year variant with 12 (or, in the case of half-periods, with 24) periods. Special periods are not restricted, that is, your fiscal year variant can have as many special periods as you want.
If the fiscal year variant is defined as year-dependent, you have to generate a new calendar assignment for depreciation period control each year (application menu: Periodic Processing
® Settings ).Definition of Posting Periods (FI Customizing)
The fiscal year variant contains the correlation between the calendar date and the posting periods. You assign a specific calendar time period to the various posting periods. You make this assignment by entering the last calendar date of each period. For a non-calendar fiscal year, you also have to enter a factor to indicate those periods that do not lie in the current calendar year (+1).
Non-Calendar Fiscal Month
If you also work with non-calendar fiscal months, the last posting period in the calendar year requires special handling. For this period, you have to make an additional entry for December 31. This means that this period requires two calendar assignments:
