NBV negative in Area 11 & Area 12

Question

HI Guys,
we have  few  assets from legacy system which are  depreciated beyond  their acquisition value and as a result NBV is negative  for Area 11 AMT and for Area 12 ACE. I n the  config the definition of dep.areas only allow positive values, I can change the values allowed to "all values" but this will also change the definition of dep.areas.and system also gives warning message,Is it  ok to change   the dep areas to all values allowed or it wil have some  effect on book area  also ??what are the consquences if I change the dep areas to accamodate negative  assets.Thanks
Regards
Shaun

Hi Shaun,
The consequence of allowing negative values is that you can post evereything. Therefore SAP don not recoment to allow negative valeus for depr. aea 01 expect of AUC's.  Generally, negative values should always be allowed for assets under  
construction. You should therefore make this setting at asset class  level (Transaction OAYZ).                                             
It is not important if the values  are positiv at the end. If the values are negativ at one time, the error message rises.          
So if the valeus are really negative:                                                                               
1) Avoid negative values                                          
2) Allow negative values         
ad 1) Reverse and post in another sequence
ad 2) In OADB or in depreciation area (XNEGA)
