SAP Message ACRSL029 - & : Choose 'Acq.only allowed in capitalization year'

Diagnosis
The ordinary depreciation key represents either unit-of-productiondepreciation or sum-of-the-years-digits depreciation.
In this case, you should choose the 'acquisition only allowed incapitalization year' option, since otherwise the asset could still havea net book value after the useful life is expired.
