Help with Business Process

Question

I am a newbie to XI world and am trying to implement the following.  Create a scenario where a HTTP client calls a BAPI (creating a PO) synchronously, wish it would have been the end :).  There 3 steps in PO creation, one is to create from one company code to another and create the same quantity and material to a vendor and acknowledge to the web client about the PO creation status.  
Since the above is a sequence and a process, I am assuming I have to use BPM capability of XI.  If answer is yes, then any business process has to be implemented through BPM, am I right in concluding this?
Am more looking at direction than any particular answers, if anyone can guide me I will find my way out.
Thanks in advance for any suggestions

Thanks for your quick reply.  But if I wrap all my logic in BAPI then there it would become a real big one and moreover there is a sequence in my process:
1) Create a PO from company code A to company code B
2) Create a PO from company code B to vendor
3) On the return an shipping notice would trigger creating a delivery and doing a goods receipt and goods issue for the two PO's created.
Since the above is a business process I was thinking it would be better if I use BPM instead of using a single BAPI for everything.  Am I incorrect in my thinking?
