reducing posted depreciation from planned depreciation and
post the differential depreciation in the current period. With
smoothing, the differential depreciation will be spread over the
remaining posting period.
You can assign depreciation keys for depreciation areas through
transaction code OAYZ. In addition to other parameters, you
are assigning five calculation methods to depreciation keys.
These are: (1) base method, (2) declining-balance method,
(3) maximum amount method, (4) multilevel method, and
(5) period control method.
Base method: The base method contains general control
parameters the system needs for calculating depreciation.
With this method, you specify the depreciation type, the
depreciation calculation method, and the treatment of the end
of depreciation.
Declining-balance method: The declining-balance method
includes both the declining-balance method and the
sum-of-the-years-digits method. The normal declining-balance
method of depreciation multiplies the straight-line percentage
rate resulting from the useful life by a given factor.
Maximum amount method: You use the maximum amount
method to specify the maximum amount up to which the system
should calculate depreciation until a certain calendar date.
Multi-Level method: Base methods for certain depreciation
calculation methods use either a total percentage rate or a
periodic percentage rate to calculate depreciation.
Period control method: To determine the depreciation start
and end dates for asset transactions, you can set an appropriate
period control in the period control method for these four
transaction categories: (1) acquisitions, (2) subsequent
acquisitions/post-capitalization, (3) intracompany transfers, and
(4) retirements.
