You can suspend depreciation by unchecking Depreciate in the Books window. If you suspend depreciation of an asset when you add the asset, Oracle Assets expenses the missed depreciation in the period you start depreciating the asset.
For table and calculated methods, Oracle Assets calculates depreciation expense for the asset based on an asset life that includes the periods you did not depreciate it. If you suspend depreciation after an asset has started depreciating, Oracle Assets catches up the missed depreciation expense in the last period of life.

For flat–rate methods, Oracle Assets continues calculating depreciation expense for the asset based on the flat–rate. For flat–rate methods that use net book value, Oracle Assets uses the asset net book value at the beginning of the fiscal year in which you resume depreciation. The asset continues depreciating until it becomes fully reserved.

Period Close
Oracle Assets automatically closes the book’s current period and opens the next when you run the depreciation program. You cannot have more than one open period for a given depreciation book.

Year–End Processing
You can close the year independently in each depreciation book. The depreciation program automatically resets year–to–date amounts on a book the first time the depreciation program is run on that book in a fiscal year. Oracle Assets automatically creates the depreciation and prorate periods for your new year when you run depreciation for the last period of the previous fiscal year.
Verify the depreciation and prorate periods that Oracle Assets creates before you enter transactions in the new year.

Prior Period Additions
If you enter an asset with a date placed in service before the current accounting period, Oracle Assets automatically calculates the missed depreciation and adjusts the accumulated depreciation on the next depreciation run.
If you provide accumulated depreciation when you add the asset, Oracle Assets does not recalculate the accumulated depreciation. It accepts the amount you entered.

For table and calculated methods, even if the entered accumulated depreciation differs from what Oracle Assets would have calculated, Oracle Assets does not depreciate the asset beyond the recoverable cost. If the accumulated depreciation is too low, Oracle Assets takes additional depreciation in the last period of the asset’s life so that the asset becomes fully reserved. If the asset’s accumulated depreciation is too high, Oracle Assets stops depreciating the asset when it becomes fully reserved, effectively shortening the asset life.

Prior Period Transfers
If you back date an asset transfer, Oracle Assets automatically reallocates depreciation expense by reversing some of the depreciation charged to the ”from” account, and redistributing it proportionally to the ”to” accounts. Retroactive transfers do not impact the total depreciation. You cannot backdate a transfer to a prior fiscal year.

Prior Period Retirements / Reinstatements
If you back date a retirement, Oracle Assets automatically adjusts the depreciation for the year by the appropriate amount, resulting in a one–time adjustment in depreciation expense for the period. Oracle Assets then computes the gain or loss using the resulting net book value.

You cannot backdate a retirement to a previous fiscal year, nor can you reinstate a retirement performed in a previous fiscal year. Prior Period Amortized Adjustments If you back date an amortized adjustment, Oracle Assets automatically calculates depreciation from the retroactive amortization start date, and adds the retroactive depreciation to the current period. You can perform multiple prior period amortized adjustments to an asset.

Credit Assets
You can enter a credit asset as an asset with a negative cost, and Oracle Assets credits depreciation expense and debits accumulated depreciation each period for the life of the asset.
