When the Web Services engine acts as a consumer of Web Services (that is, when Adaptive Server queries Web Services for the results of web service calls from any external services available on the Internet), Adaptive Server can make requests from any Web Services engine that is defined in its sysservers table.
When the Web Services engine acts as a producer of Web Services defined on Adaptive Server, the Web Services engine is aware only of the Adpative Server defined in its properties file, and can request results from only this Adaptive Server.
