B2B add-on

Hi,

We all know that B2B scenario involves Party to Party  communication as the systems involved

in message exchange are in different landscapes.We also checkbox for sender uses virtual receiver

while creating receiver determination.

We have one B2B scenario where (EDI to IDoc-XML)  parties are not  used.

Does B2B add on eliminates the need for party to party comunication?
