Asset sales without customer is posted as Gain Instead of Loss

Hi,

Here are the details. Company Code 100

APC of aset in Dep area 01, 15 , 91 is 489

Deprecation posted is 318 in Area 01. and Fully depreciated in 15 and 91.

In ABAON transaction, (Trading Partner 200)

when the aset is sold without customer with Revenue From NBV - Area 91 is selected, In stead of considering a loss in Area 01. The sale is posted as a gain.

Accounting entries

Aset Cr 489

Acc Dep Dr 318

Intercomp gain Disp Other Aset Cr 171

Intercomp Rech.gai. disp. Fi Aset DR 342

What I would I ideally expect is the following transaction as the

Aset Cr 489

Acc Dep Dr 318

Intercomp loss Disp Other Aset Dr 171

what did I miss on this is a big question.
