[NWDS] How to get webservice endpoint from difference system and client ?

Hi,

I need to call webservice from my code.

I have to created new model from my project below.

and then I use local wsdl file (for example)

when it done new model will show in my project.

and I can see default webservice endpoint.

and now I can developing with this model.

Question is : if I have same service but it on difference system and client as example

http://yyyy:8000/sap/bc/srt/rfc/sie/test_ws_test_abc/400/sie_test_ws_test_abc/sie_test_ws_test_abc

http://zzzz:8000/sap/bc/srt/rfc/sie/test_ws_test_abc/800/sie_test_ws_test_abc/sie_test_ws_test_abc

How to get webservice endpoint for each system and client ?

I don't want to change target address in the model. I looking for some coding or some configration for flexibility.

Thanks in advance
