Requesting SOAP 1.2 service from SAS 9.4 (problem with overwriting SOAP Envelope)

[kovalzdw]

Hi Everyone,

I have SAS DI Job which is responsible for requesting SOAP Service using PROC SOAP. Recently this service was upgraded, what lead to minor changes in it's request. 

Main issue that occured was to change namespace in SOAP Envelope from this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

to this:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">

SOAP Envelope is defined in "data _null_" statement where I prepare whole request body. At first I changed SOAP Envelope as in the above code, but when I looked in service logs I noticed that SAS automaticly wrapped my prepared request in another SOAP Envelope, which then looked like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
	<soapenv:Body>
		<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
			<soap:Header/>
			<soap:Body>
				...
			</soap:Body>
		</soap:Envelope>
	</soapenv:Body>
</soapenv:Envelope>

The way I request this service is quite simple and looks like this. I replaced content of parameters, but I believe they are correct.

proc soap in=request
	out=response 
	url="XXX" 
	soapaction="XXX"
	webauthdomain = "XXX"
	debug="/tmp/soapSPLDAS.log"
	; 
run;

As I found out later, the difference in namespaces may be a consequence of upgrading SOAP version from 1.1 to 1.2. SAS version I'm currently using is 9.4M7.

Now it all breaks down to question, how can I request SOAP service with this change in namespace? Can I somehow owerwrite whole SOAP Envelope? Is there a way to change SOAP version to 1.2 in SAS so I can use different namespace in envelope? 

Please let me know if I should provide more information.

Thanks for Your help.
