How does my configuration connect to company code 1000 , group asset 3005 and Depreciation area 20?

Hi

While creating a group asset at AS21, I  encountered with the following error message

No depreciation area in company code xxx allows group assets.

Message no. AY160

I checked at Tcode OAYM for group asset check box . Entered the check in the checkbox on Depreciation Area (o1, 10 and 32) and when tried to save it

I am getting another error message

Company code 1000: Group asset 3005 manages dep. area 20

Message no. AC715

Diagnosis

Company code 1000: Group asset 3005 still manages depreciation area 20. For this reason, you cannot delete the group asset indicator.

System Response

The data is not saved.

Procedure

There are two options:

1. Set the indicator for managing group assets.

2. Deactivate depreciation area 20 in group asset 3005 and in all others that manage this depreciation area (

Change group asset: master data

1. ). Then you can delete the indicator for managing group assets in depreciation area 20.

How does my configuration connect to company code 1000 , group asset 3005 and Depreciation area 20?

I am totally lost here.
