Document Splitting with Different Business Area

HI

I have a situation, where i need to create a new document type and it needs to be configured in such a way that vendor invoices and credit notes can be booked with the correct doc splitting and using different Business Areas.

I like to know if this is possible, and if yes how.

Earlier the client used to post the transactions, with different business areas, as we get only a warning message to reset the business area of the vendor.

Now that we have activated New G/L accounting, with document splitting we get the warning message,

but then the profit center will not balance, so we have an error.

The client requires that they need to post to a different business area, and the document splitting should happen.

Any suggestions on this will be great.
