unit-of-production depreciation

I need to define a new method of depreciation (unit-of-production depreciation)

I use depreciationkey Z1R1


Depreciation type : ordinary depr

Phase: from start of depreciation

Base method: ZA01 (a)

Decl.-bal.method: 001 (b)

Prd contr mehtod : ZA01 (c)

Multilevel method : 001 (d)

(a) ordinary depr; perc of remaining life calc.from depr conversiondate

treatment: all NO

(b) standard SAP

(c) depreciation starts beginning of month: acq: 01, Add: 01, Ret: 01, Tm:01

(d) 001; validity start 2 ( from ordinary depreciation start date)

Class: straight line depreciation

Change method : xxxx

Change over % rate : xxx

Multiple shift: no effect on depreciation and usefull life

scrap value: consideration is controlled by cutoff value key

shutdown : no

When I start t/c AO25 and fill in year 2008 per 1; tot units 24; rem units 23 per. Unit 1

An errormessage appears: corresponding entry in u201Cdepreciation keyu201D is missing

What did I do wrong or what needs to be done and where ?

Kind regards

Hi Hans,

I am pretty convinced that your base method is defined incorrect. I think you used percentage from useful life in there. But if you want to depreciate according to unit-of-production method, you have to setup "No of units/total no of units" or "No of units/remaining units".

Otherwise a depreciation key which has this base method assigned will not be considered as a unit-of-production key, and the error message would in fact raise correctly that units can not be maintained for such a depreciation key.
