Calling a BAPI Synchronously from a SAP System

I had set up an RFC Listener for the SAP System.
I had set up a corresponding RFC destination on my SAP System. The Connection is ok.

I had written a program in SE38 which was given the webMethods SAP Adapter user guide.

In the book the receiver value was given has SAPADAPTER. I could not understand SAPADAPTER should be maintained in SM59 as alias to the SAP Adapter.

I had created an RFC Destination as SAPIS1.

Please clear the above problem.

Thanks in advance
