Thanks in advance.

Consuming external web service directly without xi system in between.

u2022     Create Enterprise Service-> Choose object type as u201CService Consumeru201D
u2022     Select URL HTTP destination in the next step
u2022     Give the WSDL url in the url point
u2022     Give any package name or store it in the local object.
u2022     Corresponding proxies and data types will be generated inside the enterprise service tag
Code sample for invoking the service via report.
u2022     Create an object of the client proxy type here itu2019s io_clientproxy.
u2022     Declare input and output parameters as per the structure of the service input/output parameters.
