How to transfer the webservice username/PW to the RFC call in PI 7.0

Question

Hey,
I would like to transfer the username/PW, which is supplied, when a specific web service is called. The web service is supposed to be exposed on PI 7.0 and will transfer the request to a function module in ECC 6.0 via an RFC communication channel in PI 7.0. Typically, you specify the username/PW in the RFC comm. channel in PI, but how do I dynamically specify the received username/PW from the web service call in that RFC call to ECC 6.0? Maybe SAML is the answer, but it seems a bit cumbersome in my case.

Hi Michal
Thanks for the link. I have been looking for blogs/material on how, in a mapping in PI, to place the value of SRemoteUser in a field in the target message but without luck. Is it really the case, that I have to use batch input in order for it to work?
What is wrong with this code in a UDF where there is no input variable. Will it work?:
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/SOAP", "SRemoteUser");
String WSuser = conf.put(key);
return WSuser;
Or should I skip this UDF all together and in stead use Variable Transport Binding and set XHeaderName1 = SRemoteUser   ?
Looking forward to your book on iDocs in August
