Intercompany transfer order fails to generate payable invoice

We are processing an intercompany transfer order. The intercompany receivables invoice was created. The interorganization transfer shipment source event is 'in progress', but the Intercompany Payables Invoice task is in error. There are no error messages available. We have the 'Use intercompany accrual charge account from receipt accounting for payables' set to yes. The accrual account exists in Receipt Accounting and has been finally accounted, but SCFO has still failed to create the AP invoice. I'm left with the red X on the payables task with no hints on where the problem lies
