intercompany billing issue

hi guys

I have made all the settings for intercompany... when i raise the order and when i change a plant in procurement tab it is giving error message

No business area can be determined for item 000010

Message no. V1599

Diagnosis

The system could not determine a business area for item 000010. The item has plant ABC and is assigned to company code ABC for which a business area is required. This is caused by incomplete settings in Customizing.

System Response

The system does not allow you to create the item.

Procedure

Before creating the item, make sure that you have completely maintained business area assignments in Customizing.
