Communication between RPC XML interface and ABAP.

Hi all,

how to consume the webservice (BZSt: USt-IdNr. Bestätigung) in SAP system which has RPC XML interface.

There should be a communication between this website and my ABAP program so that i can send the input data and receive the result in the ABAP program.

i tried searching in the forum but only found webservices using WSDL.

Thanks in advance,

regards,

NarsiReddy.
