Use
You make specifications for fiscal years and posting periods in the SAP R/3 System in the Customizing for Financial Accounting. You define the relationship between the calendar dates and FI posting periods in the fiscal year version in the global parameters for the company code. For this reason, you can enter all dates (for example, the asset value date of the posting) as calendar dates, even when you are using a non-calendar fiscal year. Based on the fiscal year version, the system determines which posting period is involved.
Features
These settings are, in general, also binding for Asset Accounting. The depreciation periods in Asset Accounting then correspond to the posting periods in Financial Accounting. It is usually not necessary to create a separate fiscal year version for Asset Accounting.
Period Control
The period control in the applicable depreciation key determines the start and end of depreciation for asset transactions (see
Period Control). In the period control, you determine the relationship between the calendar period in which the asset transaction is posted, and the depreciation period for the calculation.These calendar periods are independent of the posting periods in Financial Accounting. The only restriction is that the beginning of the first calendar period and the end of the last calendar period defined in a period control have to match the start date and final date of the fiscal year in Financial Accounting.
The graphic below shows how the system determines the period for the start and end of depreciation using period control in the internal calculation key and the fiscal year version from Financial Accounting.

Period control
Period control 4 (first year convention of a half year) applies to the transaction type "acquisitions" in this example. The period control is defined so that depreciation is calculated starting with period 00 (January 1) for acquisitions up to June 30. For acquisitions that take place between July 1 and December 31, the system calculates depreciation starting with period 06 (July 1). Fiscal year version K4 corresponds to the calendar year.

Period 00 is interpreted as the start of the year, not period 01.
