How to create 2nd web service proxy in SAP?

Hello all,

for an external web service we have created a proxy class via SE80 (this works fine). Now I want to add another proxy class that should target the same web service, but at another address (it's a test machine). The problem is now that SAP tells me it can't create this 2nd proxy, because the namespace is already in use (which is correct, because of the 1st proxy in SAP).

However, I need to create a proxy to this 2nd web service with the same name space (unfortunately they can't change it). What can I do to solve this problem, any ideas?

Thanks in advance for your help!

Kind regards, Matthias
