Multiple PI system

hey all,

in the current scenario, there is an ERP system, which is already configured for proxy connection to a PI system PI1. there is also another PI system PI2.

in a second scenario, ERP system needs to be connected to PI2. now since ERP system is already connected to PI1, through proxy configuration, so the only option available is: ERP -> PI1 -> PI2 -> 3rd party system. So how to configure this scenario - meaning should PI2 be made as business system or business service and why?

the PI1 and PI2 are based on 7.4 single java stack system.

also is there any way to have ERP - PI1 and ERP - PI2 both configurations parallelly active in proxy configuration, so that the above scenario can be reduced to ERP - PI2 - 3rd party system?

all helpful replies will be appreciated.

    Your ECC system can directly connect to multiple PI systems. Check this blog for the same : Connect SAP Application System to multiple SAP PI Integration Server - Variant n°1

    • Hello Stewart,

      The Sender Uses Virtual Receiver is mandatory - You do this to enable the PI System identify which ICO it has to forward the message to. All you need to do is to put the Virtual Receiver as *.

      Once you do this, you will still need to key in the Receiver System in the Receivers Tab and here you can provide your actual receiver.See below screen shot

      Couple of notes

      • In ICO 2 while i have asked you to make sender uses virtual receiver with receiver as *, you can also make this as the same receiver Business System name as ICO 1. Making it * makes it easy as you only need one business system from PI 1 here.
      • In ICO1, you can use Header Mapping for Sender and Receiver System if you want to change the Business System Names. But they need to be then the same in PI 2 ( Sender System and Sender Uses Virtual Receiver )
      • If you want the Sender system to be called PI 1 in ICO 2 then you can do a Header Mapping in ICO 1 and then use the PI1 Business System as the Sender System and this can then be used in ICO 2.

    Hi Stewart,

    Just to add, from the link what Bhavesh has provided.

    You can keep the proxy connection active for both the PI system, but you can view only one PI system interfaces at a time and this depends on the connection details provided in the RFC destination named SAP_PROXY_ESR.

    So your query of connecting ERP->P1->P2 is not necessary. You can have 2 separate connections -

    ERP-> P1

    ERP-> P2
