We have a customer who purchased ESI to integrate with their SAP (Windchill 10.2M020). However, they do have security requirement to pass information through SAP PI only. Is there any way to use the TIBCO (Available with ESI) and make it talk to or work with SAP PI? can we pass information from TIBCO to SAP PI and have SAP PI talk with BAPI? If yes, whats the effort like on the TIBCO to SAP PI piece and SAP PI to SAP?
