Please review note  549182  FAQ: Business Area Accounting
in particular see point  3.

With customer and vendor items, why can you not enter a business area?
Answer:
Open items are assigned to business areas depending on the expense and
revenue items of the invoice.
Because of this dependency, open items can be assigned to several
business areas. Thus the assignment is no longer unique. There is a
function available in the balance sheet adjustment that enables a
subsequent assignment.
With a unique dependency, the business area is copied into the open
items not assigned to a business area during the posting of the
document.
Also consider SAP Note 41294 in this context.
