Sequenced Sending of Inbound XML Messages

Question

We are using ABAP proxies which communicate through XML messages. The current problem that we are facing is that from one INVRPT EDI message, it has to be transformed to two different messages and be sent to the same receiver. The main obstacle is that the first type of message should be processed first before the second type should be sent. If the second message is received by the receiving SAP system, that message will be invalidated and raise an issue at the receiver side.
The current solution we are looking at is for the receiving SAP system to send an acknowledgment message however, as I looked through BPM, it is only capable of having one sending step (we need to send two messages from one outbound message however at different time intervals).
Any idea on how to circumvent the problem? Your help will be greatly appreciated.
Many Thanks and Best Regards,

Hi Udo,
Basically, a customer sends an EDI ORDERS file via AS2. When XI receives the message, it will transform the message to 2 XML messages, one is for order promotion while the second is the actual order XML. The order promotion XML should be sent first to SAP SNC (Supply Network Collaboration) for it to be processed there. Now, once the promotion is in place in SNC, that is the only time the order XML should be sent. If the order XML comes first before the promotion, the message will be invalidated and SNC will raise an error. We are using XI Adapters and the ABAP proxies are SAP predevelivered content for XI (so that we don't need to configure or recreate the XML structures in XI).
