Point to different endpoints

Hi experts, I am new with Java WebDynpro and I have the following problem.

I have created a new WD that use a service (a SAP R3 service).

I have imported the service model and created the service group.

I call the service and everything works as expected.

Now I want to call the same service but in another system (the quality system).

How it can be done ?

I need to change the Service group parameters (i.e. the service provider) ?

I need to use Loglcal port ?

I need to use Destination ?

Please help.
