Difference in Depreciation Amount in Area 01 and Dep Area 32

I am having an issue with depreciation amount posted in Area 01 and Area 32.

Group currency, local currency and document currency are in USD.

The difference is due to different start dates of dep in Area 01 and Area 32.

There is difference of about $15000 in different assets accumulated over the years and

the client wants to adjust the difference now by JV.

Dep in area 32 is excess and it has to be adjusted to match with Area 01.

How can I adjust the difference ? I want to write down $15000 in Area 32 only -to

match with Dep in Area 01.

Appreciate your help.
