Question on ESA

Hi All,

I have gone through the example "POCreate" in the eLearning sessions of the ESA.

Question :

If i have a FM in a R/3 system and i would like to provide the FM as a service to the outer world so that they can access the functionality provided by that FM through a webservice.If i can create such a webservice then we can call those kind of services as ESA .Is that correct ??

Please correct me if i am wrong.

Thanks & Regards, Anilkumar
