Hi Mark,
I am not sure I understand your suggestion.
I look at the message in SXI_MONITOR (in PI). Under the Call Adapter -> SOAP Header nodes, there is an entry: Reliable Messaging and when I click on it, I see the following:
<!-- Call Adapter -->
<SAP:ReliableMessaging SOAP:mustUnderstand="1" xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
<SAP:QualityOfService>ExactlyOnce</SAP:QualityOfService>
</SAP:ReliableMessaging>
If this is not what you mean, can you please give me more details as to your suggestion?
Regards.
