ABAP & Java Concepts required for SAP-NW XI/PI

Hi Experts,
As a fresher, I want to start a career in SAP ans SAP Netweaver- XI/PI. After going through some blogs, forum, sap stuff etc, I came to know the prerequisites for XI is both ABAP and Java...
But I am not sure which concepts in ABAP and Java are required for an SAP XI consultant, as I see SAP itself is an Ocean. So Apart from XI concepts , what are all the concepts needed in ABAP and Java.
As for XI concepts are concerned there is a lot of stuff in SDN itself. Only thing is, one shd have patience to search and proper guidance while learning.
Regards,
Guru

something quite common a question but here is a small desc.
ABAP -
for scenarios involving, IDoc, RFC, ABAP proxies and ABAP mappings
Java -
Core java - UDFs in graphical mapping
advanced - java mapping, adapter modules, java proxies etc

Gathering Technical and Business Requirements for SAP PI

I need to some documents and tools, or interview guide & questionnaire to gather the stakeholders' technical and business requirements for SAP PI

Thanks for the links,
I am quite new at SAP and currently trying to elaborate should i use SAP PI or not based on my project stakeholder's requirements.
And my biggest problem right now is how to capture technology and business requirements and match them with SAP PI
I plan to use this format while requirements gathering about integration platform:
1- Draft Requirements
Q- What is the names and status of sending and receiving application and how they will be used
2- Detailed Requirements
Q- Connectivity, Administrative and Business related questins
3- Administrative and project management information
Q- Which applications are involved, who is the original supplier? Who is technical contact at the supplier
4- Business requirements
Q- Questions about the information flow which will support some business processes
5- Connectivity to applications
Q- Questions about connectivity mechanism, file formats (flat file or XML or something else), data access methods and so on
What do you think about the general concept?

If the server is for Production incease the RAM accordingly.
For Portal RAM is very crucial,as SAPJ2EE Engine uses lot of RAM.

Is any Programming knowledge require for SAP MDM people ??

My name is Balu completed Mechanical Engineering. Am Interesting to learn SAP MDM. Is there any Programming Knowledge require for to learn SAP MDM. Please reply my Question.
Thanks In Advance,
Best Regards,
Balu
Hi Balu,
It all depends on the kind of role you aim at or how you want to sell yourself.
I dont think programming knowledge is required for core SAP MDM related work but it all depends on the role in hand,project requirement,landscape,customization etc.
I will like to add that SAP NetWeaver Master Data Management (SAP NetWeaver MDM) can provide a single version of master data for supplier, product, customer, or user-defined data objects in heterogeneous environments.
It is not only a tool but a part of strategy.It has to interact various SAP as well as legacy systems for data related operations.
SAP provides its users with set of APIs which one can use to achieve customization as per their requirement.
There are ABAP,JAVA and .NET APIs provided by SAP for this purpose.
In all,having a coding experience in any of the above languages would certainly be a plus.
Hope it help!
Thanks,
Ravi
