proxy to web service scenario in PI 7.1 using SOA

Hello Experts,

I am working on PI but very new to SOA concept.

Now my client wants to do the Prototype in which we have third party system who can consume web service and ECC system who will provide the information.

Third party <-> Web service <-> PI 7.1 <-> ECC Proxy

Can someone please provide me some step-by-step kind of guide for this type of scenario?

I need to implement SOA in this, i mean have to publish the web service on Service Repository and stuff.

I am not pretty sure that what all the things i need to do for this.

Any help is greatly appriciated.

Thanks,

Hetal
