Changing Fixed Assets useful life according IAS rules

Hi all,

According to the new IAS rules (International Accounting Standards) when an asset's useful life (currently with straight line depreciation) is changed we have to distribute the "net book value" (remaining depreciation to be posted) between all the remaining months in the same proportion.

Currently, SAP standard calculates the depreciation as the difference between the posted depreciation throughout the previous months and the amount that should have been depreciated with the new useful life, and it assigns this calculated amount in the current month when the useful life is changed.

We have checked that the remaining depreciation to be posted can be distributed equally over the remaining periods of the fiscal year by marking the "smoothing" flag through transaction OAYR per company code, but we need this amount to be distributed over all the remaining periods for the new useful life (not only over the current fiscal year).

Please find below an example to try to clarify my query:

A fixed asset with str.line depreciation has the following values:

Acquisition value: 12000 eur

Useful life: 3 years

Depreciation per year: 4000 eur.

The asset starts to depreciate on 01.01.2008 and its useful life is

changed to 2 years on 01.07.2008. On that moment the net book value is

10000 eur.

SAP adjusts the difference between the amount that should have been

depreciated with the new useful life (3.000 eur) and the real amount

posted (2.000 eur) = 1.000 eur depending on the "smoothing" flag:

1. If the flag is not marked: SAP assigns 1.500 eur (500 eur (6.000/12)

+ 1.000 eur from the difference) on 01.07.2008

2. If the flag is marked: SAP distributes the difference between the

remaining periods of the current year (from July to December) and it

assigns 666,66 eur per month (500 eur + 166,66, obtained from 1.000

eur/6 months).

But we need the same depreciation amount distributed over the remaining

months: 10.000 eur/18 months = 555,55 eur/month.

Has anyone come through the same problem before?

The only solution I can think of is transferring the asset values to a new one. Or maybe a user exit.

Any feedback will be much appreciated.

Thank you very much in advance. Best regards

    do you use the new depreciation calculation functionality with time-dependent depreciation parameters? You could create a new depreciation parameter interval as of 7/2008 in your example, and that should distribute the remaining net book value then over the remaining life.

    Of course a transfer to a new asset is also possible.
