Hi,

that is because you have basic authentication enabled in order to access the WS.

For example, if the WS is deployed to MS IIS, open IIS console -> Web Site -> Scroll down to the WS -> Authentication -> Basic Auth

Now, from PB WS clients you have two options:

1. using the SoapConnection class:
   conn = CREATE SoapConnection
   conn.SetBasicAuthentication('', "username", "password")
2. using a WS datawindow:
   lws_connection = CREATE wsconnection
   lws_connection.authenticationmode = "basic"
   lws_connection.username = "username"
   lws_connection.password = "password"
   dw_1.SetwsObject(lws_connection)
   dw_1.retrieve()

Hope that helps.

Cheers,

Marco
