Using Dynamic partner link in BPEL 12c

Hi,

I'm trying to use Dynamic partner links in BPEL12c ( Oracle SOA 12.2.1.2.0) in a scenario where a BPEL process should dynamically invoke a provider service based on a parameter at runtime. Below are the steps that are followed.

1) Created an abstract WSDL with the Port Type and Binding details and stored it in MDS.

2) Created Provider service A based on the abstract WSDL and deployed it on the server.

3) Created Provider service B based on the same abstract WSDL and deployed it on the server. I used the same WSDL  service name(service entry point) for both the providers.
