Hi Amit, i'm following the SAP PRESS book PI practical exercise or something like that, I begin with creating a product, then a software Component and set this as installed software in the ECC sld config, then I import to the ESR an ECC WSDL and then I create manually a service interface assigning the data types the import of the wsdl generate.
Then I guessed that I could begin with a flow or almost set one of the systems and the previous interface generated in the ESR, but when I try to assign the published interface in the ESR to the flow and to the ECC side I didnt find any interface yet...
