It is my understanding that the Web Service is coming with WAS 6.40. This wizard will allow for mapping between the function's internal interface and the external interface that you would like to expose via the web service.
That said, WAS 6.20 does have the capability to call ABAP functions via SOAP. Take a look at the SICF nodes /sap/bc/soap/rfc and /sap/bc/soap/wsdl11.
Once you activate the nodes in SICF, you can access the WSDL for a list of functions by an URL such as:
<b>http://bt4:8080/sap/bc/soap/wsdl11?services=RFC_READ_REPORT,RFC_SYSTEM_INFO</b>
The functions that you want want to generate the WSDL for are listed separated by commas.
Cheers,
Scott
You can find a nice presentation about WebServices in WAS 640 in the Teched sessions (OSI202 - Building Web Services with ABAP and SAP Web Application).
For WAS 6.20 there is a nice package (Web Service Workshop - TechEd 2002.zip) with full of info in the service.sap.com/connectors -> SOAP Processor ->Media Library section.
