How do we connect SAP PI and SAP Netweaver Gateway

[Former Member]

Dear Experts,

I have seen many blogs and information on two SAP products ,SAP PI and SAP Netweaver Gateway and there has been a very good document by William on when to choose SAP Netweaver Gateway and SAP PI as both are integrating tools.

I would like to know whether it is a good practice to have something like SAP(ECC)-SAP Netweaver Gateway-SAP PI-thirdparty systems.We need to have this scenario as all data to be interfaced needs to go through SAP NW Gateway.

Because of the error handling capabilities which SAP PI offers we would like to know whether it is technically possible to connect from NW Gateway to SAP PI.With newer versions of SAP PO we have that capability where we have java gateway incorporated with SAP PO and Rest adapters which make that possible to connect to SAP Gateway.

Could experts please throw more light on the connection between sap pi (version 7.1) and sap netweaver gateway if we want to have integration scope SAP ECC-SAPGW(Hub)-SAP PI-Thirdparty and how do we achieve it .

Thanks for all the help and suggestions.

Hi Shaik

I dont understand why would you want to connect Pi and gateway ?

They are 2 different software solutions . PI is used for integration and gateway is used for displaying data on a user interface. I also went through the williams link you have mentioned and it says as below and sums it all.

"Does SAP NetWeaver Gateway Replace any Existing SAP Software?In a word—No. SAP NetWeaver Gateway is not designed to be a channel for transactional applications, nor is it designed to replace existing middleware like SAP NetWeaver PI. In addition, applications built on SAP NetWeaver Gateway are not designed to target integration scenarios. user-facing applications "

In my current client landscape we have both the systems installed where gateway offers a better front end capability for CRM and Hybris system and PI is used for system integration between CRM and 3rd Party and also between CRM and ECC systems

Using just the PO system can help in activating OData as mentioned below but many of the capabilities of gateway do not work

"Customers who are already using SAP Process Orchestration as a middleware solution can now activate the OData generation of ABAP-based SAP Systems directly inside PI. This has the advantages that no SAP Gateway hub system is required any more (which saves cost for hardware and operations) and also strengthens central governance."

refer this link as well which helps you exposing gateway services from PO
