Intercompany SLA

Hello,

We would like to make appear the cost center in the accounting journal entries. But it does not work for the intercompany transactions.

From the receivables side, when we generate the invoices (non intercomapny) , we have to insert the cost center on the attribute 5.
And from the payables side, generally, for the non intercompany invoices, the accounting entry took the cost center from the purchase order charge account indicated on the PO . But with a transfer order, we do not have these indications, I mean the attribute 5 and the purchase order charge account.

How can we solve this problem, is it a way to retrieve the cost center from the transfer order?
