Can more than one SAP ERP system connect to the same PI system?

HI Experts

Well i am new to SAP Process Integration 7.1 and i have managed to point PI system to SAP DEV ERP , but i also want to add these other 2 systems SAP QAS ERP and SAP PRD ERP Using RFC Adapter. So is it possible to integrate SAP QAS and SAP PRD  ERP into the same PI system that is pointing to SAP DEV ERP. If possible what are the configuration steps that i should follow?.

This project implementation is based on SAP MDM 7.1/ SAP PI 7.1/ ECC EHP6.

Hi Farai,

Technically this is possible. But don't forget that all systems are then using the same ESR and ID. So changes on PI are also influencing ERP QAS and PRD. I don't recommend this. At least you should have 2 stages for PI: Development and QAS/PRD.

You just need to maintain 2 connections in ERP: ESR connection and RFC connection. For using the interfaces in PI for all 3 stages you need to create 3 different configurations in Integration Builder of PI.
