For a Fixed Asset, you expect and maintain the depreciation to be calculated over a period of 3 years. After the depreciation run, you notice that the depreciation is calculated over 6 years instead of the 3 years maintained.
SAP Business ByDesign
The depreciation is calculated over a period of 6 years because you have maintained for the depreciation, both the Useful Life Years and Periods fields. You have maintained this as follow:
Useful Life Years / Periods: 3 / 36
For the depreciation to be calculated as expected over 3 years, you must only fill one of the fields. Either, you fill the Useful Life Years as 3 years, or you fill the Periods as 36.
Note: Useful Life Years / Periods: 3 / 36 is just an example.
