Maybe I have described not so clear my problem. Because it is realy important for us I try to describe more detail:
According to our internal accounting principles of fixed assets, when
we made essential subsequent acquisition, e.g. we made repair works of
the roof of our building; we have to add those costs to initial
acquisition cost of the building, and to prolong useful life of the
building. And depreciation calculation must be calculated in this way:
Initial acquisition cost 1.000.000 monetary units (MU);
Initial useful life 40 years;
Monthly depreciation was: 1.000.000/40/12 = 2.083 MU;
After 20 years we made subsequent acquisition amounting to 200.000 MU
and prolonged useful life additionally 10 years.
So in our accounting books planned monthly depreciation after
subsequent acquisition must be as follows:
(500.000 + 200.000) / 30 / 12 = <b>1.944</b> MU,
500.000 MU net book value at subsequent acquisition day = 1.000.000 /
20
30 years = remaining 20 years + prolonged useful life 10 years
But the system calculates in this way:
Recalculates depreciation of past 20 years and posts difference with
positive depreciation value to current year planned depreciation:
1.000.000 / 40 / 12 - 1.000.000 / 50 / 12 = 2.083 - 1.667 = 417 MU,
417 * 20 * 12 = 100.000 MU
And only after that in planned future fiscal years system posts
negative depreciation. For example we made subsequent acquisition in
December of 2006:
Period Depreciaiton, MU
2006/12 +100.000
2007/01 -2.222
2007/02 -2.222
… -2.222
2036/12 -2.222
Posting like above are completely inconsistent with our internal
accounting principles. We need to avoid positive depreciation postings
at all.
We need postings as follows:
Period Depreciaiton, MU
2006/12 -1.944
2007/01 -1.944
2007/02 -1.944
… -1.944
2036/12 -1.944
How to configure depreciation of subsequent acquisitions and prolonging
of useful life according to our needs?
