R/3 to XI (Idoc to File): Do we need to maintain distribution model in R/3?

Hi All,

I have a very basic question regarding Distribution model.

My scenario is IDOC-->File ( SAP R/3 --> XI). So all I am trying to do is send the IDOC frrom R/3 to XI. ( Within XI I am going to do an FTP to the 3rd party file server)

I have created a distribution model, but was wondering if I really need to create one as message is going from R/3 to XI and not from R/3 to another R/3.

Please help let me know If I need to distribute this model to XI or to SAP production sytem or I do not need to duistribute at all for this scenario.

Thanks

Shirin
