Customer line item business area new scenario

We create a customer invoice. The sales revenue must be assigned to several

business areas. The receivable is posted without a business area as follows:

Account Business Area Amount

Customer/receivable 700.00

Revenue 200 300.00-

Freight payable 900 400.00-

Freight expense 900 400.00

Client requirement is business area should be populated in customer line item that is 200 (BSEG) table.

Its working in 4.5b but after Tech upgrade ECC6 its not working.
