Hi Chandra,

If you are starting with ESA, try exposing a function module as a web service and then cosume this in your abap program..

you can also test it as a stand alone web service.

Dear Pushkar,

Till now we are doing the following process

Generate Web service from RFC/BAPI using wizard/se80, writting a proxy and testing it. or consume it in VC.

Is the process same here also.

Does it mean if i generate web services from ECC6.0 they are called ESA Components.

Also can these be consumed in XI 3.0( as such XI 3.0 doesnt support ESA).

yes, you are right the services which generated in ECC 6.0 can also be consumed by XI 3.0 all you need to do is you have to download the WSDL file of that webservice and consume in XI to communicate to any other system.

Also one important point to be noted that XI is one of the core and important component of ESA platform for exposing and consuming webservices.

Dear Sumit

Thanks for your Info,

But one question still pops on my mind is,

if SAP XI 3.0 supports ESA,Why SAP have included the term ESR in PI7.0?

And they Say PI 7.1(to be released in sept 2007) fully supports ESOA.

its still not clear.

Hi,

The term ESR is Enterprise Service Repository, it is the same concept as the Integration Repository of XI. The difference is we use and declare contents in XI IR and those contents will be available to XI only, now SAP has build this functionality out of the box.

Now you can declare your interfaces globally in ESR and you can use the interfaces anywhere in any softwares as a webservice.

So this is the concept of ESR, if you have still any doubt then let me know.
