The same depreciation key difference depreciation value

Hi Experts,

I have set the same depreciation key in difference SAP server, net value / useful life 

When I create a new asset, ACQ : 120000, capital date 2014/07/31, Start depreciation Date 2014/08/01, Use life 1 year

The asset depreciation value is 10000 one month. Currently I set the unplan value 60000 in 2014/07/31

A Site The Depreication Value will be effected by unplan

But B Site the depreciation value still not be changed, when I created unpaln transaction by ABAA

The IMG of period control (AFAMP) & AFAMS & AFAMA are the same. Is there still any IMG will effect the depreciation value calculated?

Best regards,

Eric
