XI/PI

Question

XI/PI - what is this PI?

Answer 1

Hi,
PI is nothing but Process Integration. As XI is represented in the Process Integration layer of the Netweaver Stack, it is now PI.
There is no difference between XI 3.0 and PI 7.0. In order to bring all Netweaver releases in line with each other, SAP has released XI as PI. Now it is a part of NetWeaver 2004s.
I hope this clarifies.
SAP NetWeaver Process Integration 7.1 (SAP NetWeaver PI 7.1)
You can use the ES Repository and Registry with SAP NetWeaver PI and take full advantage of the process integration capabilities of SAP NetWeaver and leverage the benefits of the Integration Directory and Integration Server. With the ES Repository, you can start modeling your business process and designing your interfaces, data types and mappings for the message exchange.
SAP NetWeaver Composition Environment 7.1 (SAP NetWeaver CE 7.1)
SAP NetWeaver Composition Environment 7.1 offers full service provisioning capabilities, also for those who need to work with a lean development environment and do not focus on process integration. For those customers, the ES Repository and Registry offers capabilities for service provisioning and consumption.
An another interesting aspect here is the Usage profiles - The usage profiles helps you customize the tool to the use case you are working with. You can either choose to work with Service Definition mode (as in the case of CE) or Process Integration (when you are working with PI scenarios).
XI Vs PI
There is not much difference between XI 3.0 with latest Service Pack i.e. 20 or 21 and PI 7.0
The main difference between 3.0 and 7.0 is the GUI in SLD. But, it is pretty easy to adopt. All other components, e.g. IR, ID, RWB, should virtually be identical.
7.0 also contain some SCM contents not available from 3.0. For most of us, this is a non-issue.
In 7.0 we can schedule a background job and edit the payload.
XI3.0 is based on WAS(web application server)6.40 - NW2004
PI7.0 is based on WAS(web application server)7.0 - NW2004's
Service packs in 2004 and 2004s;
in 2004 - in 2004s
SP12 & < - SP04
SP13 + 14 - SP05
SP15 - SP06
SP16 - SP07
SP17 - SP08
SP18 - SP09
