Hi
SAP has introduced a new message protocol XI 3.1 (in PI 7.31) apart from the existing message protocol’s XI 3.0 and XI 2.0 for XI receiver adapter.
Below are some of the references

SAP Notes
1459464 - Optimization: HTTP 202 instead of asynchronous acknowledgement.
According to the SAP help and attached notes, there will be some improvement in the performance of the message processing (while sending the internal acknowledgement for asynchronous message) and HTTP response will be HTTP 202 instead of HTTP 200.
I did a test (by building a file to ABAP proxy scenario) with 20 MB of file to quantify the performance of this new message protocol (XI 3.1) comparing with the existing message protocol (XI 3.0) in XI receiver communication channel (XI adapter). But, I didn’t see any difference in the time taken by the messages to get processed.
When I have checked the trace, the received HTTP response is HTTP 200 instead of HTTP 202.
Please let me know whether I'm missing any setting that needs to be done in PI or ECC in order to use XI 3.1 message protocol to get the HTTP 202 as a response?
