A few days ago I had a client request, which was to generate a proxy based on another proxy, because I had no corresponding WSDL.
Then I happened to find a way to get the WSDL generated proxy and after some time I found a way:
1-Go to transaction “SE80” and open the proxy object:
2-Go to “Utilities->Settings…”:
3-Go to last tab “Proxy Generation” and check the option “Show XML/WSDL Tab in Proxy Editor”:
4-The proxy WSDL file appear in the tab “WSDL”:
