Force an application acknowledgment for an FTP adapter

Question

Hello,
I am using XI 3.0 and I need to find a way to create an application acknowledgment from an FTP adapter.
Here is what I need to happen:
When a PO is created in R/3 we need to send a transportation order request (TOR) to a trucking companying offsite.  They will receive an XML file via FTP.  Then they will process the TOR in their system and create an application acknowledgment to inform us of a success or failure.  The acknowledgment will be in their "out" folder and our XI system will pull from the "out" folder every 10 minutes.  When we receive the acknowledgment we need to send an alert if the acknowledgment informs us of an error or if the acknowledgment tied to a TOR does not arrive within an hour.
Right now I have:
R/3 to XI as a proxy
XI to FTP folder as a FTP adapter
The problem I'm having is trying to come up with the best way to receive an acknowledgment. 
Any ideas?
Thanks,
Matt

Hi Matt
Now looking at your requirement to create a Z table in XI.
You can create a Z table. but challenge i see in implementing this is your soruce send message and wait for a response and file need to be picked in the timeout configured. Else the message itself will fail.
Here three possibilities
1. Using ABAP mapping you load the message ID in table. But holding source message for response is a challenge as well as Sync and Async bridginig is another
2. Doing an ABAP mapping and request response bean with file adapter but you need to raise alert when it fails and need to generate response in either case.
3. use of BPM. - creating a Sync - Async bridge for this and mapping/RFC to capture message ID and collect response.
Use of BPM is a proffered choice in my understanding.
