SAP Note 13536 - Incorrect depreciation after shortened fiscal year

Symptom:

After a shortened fiscal year, the depreciations were calculated incorrectly. The error particularly occurs with the "Total percentage in tax concession period" method, for example, depreciation key S7DA, calculation key 5100.

Cause and prerequisites

When setting up a shortened fiscal year, the levels of the calculation rules used must be adapted. In particular, the last level must be lengthened if a net book value is still present at the end of a shortened tax concession period as a result of reduced depreciation in a shortened fiscal year. Please refer to the corresponding chapters in the organization manual of Asset Accounting.

Solution
Correct the definition of the calculation key.
Ex. S7DA -> Calculation key 5100:
Under -> Levels, change the following line: (line 5)
from
Acq.yr Val.date Base value Reduction Percent
9999 5 0 01 acquisition value 0,0000 100,0000
to
9999 999 0 01 acquisition value 0,0000 100,0000

Key word: calculation key.
