SoapUI on Jenkins with global variables (auth)

Hello, I have project for soapUI that contains global variables for username and password. 

 

${#Global#username}

Now I have setup to run tests on Jenkins, but it fails to authentication error. I need somehow to pass those global parameters.

I have set Jenkins job configuration, enable "This build is parameterized" and typed Name same as my variable 

username

 and value for it. But it did not work, test failed, because I see username is empty while trying to call web service.
