R/3 connected to multiple XI instances

Can a single R/3 instance be connected to multiple XI instances at the same time? If so are there any limitations and is there any special considerations that should be taken into account?

    using XI protocol you can be connected only to one instance

    Limitation is in transaction SXMB_ADM where you have to put integration server destination.

    Of course you can connect R/3 to many Integration server instances but than you have to use adapters.

      When you are speaking about interfacing the system in case of SAP R/3 you are actually interfacing using Applications that you have created which might be IDoc, Proxy or RFC.

      In case of IDoc you can create multiple Partner profiles and then depending on which XI system you want to use, use the corresponding Partner profile, LS and Prots to sent the data.

      In case of triggering RFC, you can mention the correct RFC destination name that u have created for connecting to each SAP XI system.

      For proxy i think one R/3 system can be connected to only one XI system. But I am not sure about this as I have not tried to configure to system. You need to check on this.

    In any integration solution design, it's always better to have only one Broker to centralize all the messaging part. But if you have n applications running on R/3 and each one needs a dedicated XI, I don't see why not.

    I don't know about IDOC's and I'm not an Abapper as well, but from my view of the scenario, when defining RFC destinations, you can create n destinations, one for each XI, but you'll be able to call only one of them from each RFC call that you have. Depending on your solution, you could determine the destination dinamically.

    You'll need kind of a broker functionality in R/3 in order to connect it to the different XI's. :/ Kinda messy, I'd say.
