Structure RRC has default values set up in Enterprise Services Builder (the "Default" column in "Type Definition" view).
RRC is used in an ABAP Outbound Proxy.
According to http://help.sap.com/saphelp_nw74/helpdata/en/48/591b845e024bb9e10000000a42189b/content.htm
initial values must be replaced with default values when we send data to PI (Consumer Proxy section).
But it doesn't work.
Is there a way to make it work?
