Few days back I raise a request (forum) regarding HTTP queue creation for QoS = EOIO. I spent much time on SDN just to find any hint how to create a Queue from HTTP url(Sender).
Error I was getting <b>"INTERNAL.ATTRIBUTE_INITIAL" for "QUEUE_NAME".</b>
At last I come to know that it was a bugg in XI and due to which queue was not created. Please
refer a SAP Note: 1073448(it is created just 4 days back) - Plain HTTP adapter: Queue ID is not accepted.
This is just to share little information from my side.
