According to the Spanish General Accounting Plan (called P.G.C.E. on 
Spain) the 'amortization'* accounts (280/281/282) are credited yearly 
("Se abonara por la dotacion _anual,_ con cargo a la ...") against the 
expenses accounts (680/681/682). This is done at the end of the fiscal 
year (December).

* The spanish accounting plan differences between amortizations (value 
loss due to aging) and depreciations ([revertible] value loss due to 
other causes, like stock exchange losses)

I think (I'm not accountant) that's just the case on Spain. I understand 
that for your asset bought in September 2010 it's first 'amortization' 
posting would be done in December 2010 (prorated for 3 months).

I found this 
(http://www.rankia.com/foros/fiscalidad/temas/356232-amortizacion-digitos-decrecientes) 
interesting example:

   * Asset bought on March 20th.
         o Using the 'decreasing digits method' for 12 years and an
           initial value of *1000000*.
           year 1 = digit *12*, year 2 = digit *11*, year 3 = digit
           10... year 12 = digit 1; sum of 'digits' = 1+2+3...+12 = *78*
         o Being *287* the days between March 20th and December 31th
           (*78* days from January to March 20th).
           *
           *
   * First year: On December the value loss would be:
     (*1000000* * *12* / *78*) * *287*/365 = 120969.44
     (initial value * digit / sum_of_digits) * days/days_in_year

   * Second year: On December the value loss would be:
     Up to March 19th: (*1000000* * *12* / *78*) * *78*/365 = 32876.71
      From March 20th: (*1000000* * *11* / *78*) * *287*/365 = 110888.65
     Total = 32876.71 + 110888.65 = 143764.76

   * Third year (and after): Same as the second year, but using "11"
     and "10" (or the corresponding ones) as the 'digits'.

I hope it is useful :)
