CUSTOM PROCESS AND CUSTOM APPLIACATIONS

Difficulty in reusing Aggressive development of enterprise applications along with the growth of

tools (Web services, enterprise application integration, business intelligence,

portal technology) gave rise to custom development.

EXTERNAL NEED TO CUSTOMIZE Automating an innovation in a business process that has proven successful

a best practice

Automating an important relationship with a customer, partner, or supplier.

Reducing the risk of costly errors.

Rapidly assembling information for decision support.

Capturing collaborative processes that require human beings to play

together to get stuff done.

Creating highly customized, end-to-end processes to support innovation and

beat the competition.

WHERE DID WE COME FROM?

Custom applications frequently implemented their own mechanisms foraccess control, security, and operational monitoring, instead of reusing a

pool of systems for all the functionality you needed to incorporate.

Toolkits for XML messaging and transformation, enterprise applicationintegration, Web user-interface design, and business-process

management were just baby technologies or did not even exist.

Systems for content management, business intelligence, and search werejust poking their heads out as stable commercial products.

BRINGING COMPOSITE APPLICATIONS TO LIFE: A WHOLE NEW THING

It reflects the new world in which developers arent starting from a

blank slate, but are using multiple modules or applications to buildon existing functionality.

At the enterprise level, any single developer has a difficult timeunderstanding the multiple systems, technologies, and tools that arenecessary to create a composite application. SAP NetWeaver providesa set of tools, code repositories, and visualizations that givedevelopers some perspective. They can now reuse the strengths ofthe tools that they prefer and make use of the investment in code thatthe organization has already made.

Unique

Any new application has to be created in an installable unit and thenyou have to install it, test it, configure it, operate it monitor it,upgrade it, and, eventually, retire it.

Life cycle process

You can leverage the underlying legacy applications without messingup the status quo

Greater agility

CAPABLE COMPOSITES Portal: Providing the framework for building new user interfaces and

workflow, the SAP Enterprise Portal incorporates and orchestrates

different services and processes.

Integration broker: Allowing the portal to easily access and knittogether Remote Function Calls (RFCs) and BAPI, the integration

broker helps you instantly create Web services from SAP R/3

functionality.

Support for both J2EE and ABAP development:SAP Web ApplicationServer is a powerful runtime system that hosts components based on

ABAP or J2EE technology Application platform: Providing the ability to access RFCs and BAPIs,

the application platform allows you to create and orchestrate new

Web services that you assemble by using model-driven development

to support new functionality or integrate with other applications.

8/13/2019 12ASAP (2)

9/35

Business Process Management: Providing the ability to model

business processes using special languages designed for that

purpose, often with graphical tools, so that the way applications

work can be easily modified and optimized. SAP Composite Application Framework: Using a visual tool to

extend the modeling approach, the SAP CAF allows a business

analyst to define a process and generate it without requiring

much time from a programmer.

Life cycle management: Handling the details of managingcomplex development projects across large teams in distributedlocations, life cycle management includes source-code

management, staging, customizations, and upgrades.

INFORMATION AGGREGATIONImplementing a portal gives your company a quick win because it Allows users to aggregate information from multiple systems in a

personalized and easy-to-reuse fashion.

Gives developers a simple implementation with high value.

Allows users to become familiar with the overall system how it

presents data and how it allows multiple system access in a coherent

interface.

Allows developers to add functionality without complicating user

adoption.

Is the ideal environment to bring together all the levels of acomposite application framework.

Permits personalization in environment, simple navigation,

consistent look and feel, and the ability for the end user to reuse

parts.

ENABLE TRANSACTION AS WEB SERVICE SAP Enterprise Portal, which provides the framework for

creating a new user interface that includes extended

functionality.

SAP Web AS, used to construct new Web services based on ABAPor J2EE that supplement SAP R/3 functionality with new, customcomponents. This allows the SAP Enterprise Portal access to the

widest possible variety of functionality and information. It also

brings the largest number of developers into the loop.

(Developers love being in the loop.) The life cycle management features, which keep the maintenance

of these new components and solutions under control, so you can

coordinate the work of large development teams and manage

versions and upgrades.

BEST PRACTICES OFSUCCESSFULSAP CUSTOMERS Figure out where you can apply SAP NetWeaver:

Start with answering the question Wherein my organization could

SAP NetWeaver provide the most benefits?

Know thy process:Dont assume that SAP NetWeaver is an IT solution, you need

understand only the technology. Instead one should know about

their own business process.

Set your goals:Try to understand the business benefits that you hope to obtain

from SAP NetWeaver and make goals as specific as possible.

8/13/2019 12ASAP (2)

21/35

Count those pennies:Determine whether return on investment (ROI) is a factor in your

SAP NetWeaver implementation.

Know whoswho:Identify the players and roles for all your SAP NetWeaver projectstakeholders.

Get the powers that be behind you:Line up internal support for your SAP NetWeaver project before you

get started.

Go with the (work)flow:Understand your organizations unique culture, especially its pace

and style of decision-making.

The quarterbacks:SAP account executives One person who simply must be on your SAP NetWeaver

team is your SAP account executive.

Account executive is essentially an SAP salesperson.

This personsjob is to ensure that you, as an SAP customer,

are receiving lots of good service. Your account executive is also on hand to help you

understand which SAP products and services might be

useful to your company.

He or she also ensures that you receive whatever supportyou need from a wide variety of SAP experts easily and

quickly.

8/13/2019 12ASAP (2)

24/35

Technical players: Solution engineers If a picture is worth a thousand words, how much is a

good product demo worth? SAP solution engineers can

tell us.

These technically savvy people understand the nitty-

gritty details of all SAP products and theyre ready and

willing to demonstrate the current and future

functionality of the companysproducts.

Solution engineers begin by discovering as much as they

can about your industry, company, business challenges,and technical requirements. Then and only then do they

produce an SAP NetWeaver demo thats tailored to your

specific needs.

8/13/2019 12ASAP (2)

25/35

Getting engaged:Customer engagement managers SAP customer engagement managers are responsible for

planning your SAP NetWeaver implementation.

Suppose you need consulting services from SAP during

your SAP NetWeaver implementation (and you probably

will). Well, itsyour CEM who makes all the arrangements.

These folks are on hand to make sure that your SAP

NetWeaver voyage goes smoothly, in the right direction,

and on schedule. They direct you to whatever resources

and SAP specialists you might need.

8/13/2019 12ASAP (2)

26/35

Building solutions:Technical solution architects These single- minded professionals have just one goal in

life: to help you (and other SAP customers) architect a

successful SAP NetWeaver solution.

They help provide a strategy for your SAP NetWeaver

rollout and also recommend the best approach for your

implementation.

More specifically, a technical solution architect is an expert

on SAP products having a good deal of experience with

previous SAP NetWeaver implementations.

This person has already discovered the shortcuts, figured

out to avoid the pitfalls, and can guide you on the most

direct route.

8/13/2019 12ASAP (2)

27/35

SAP consultants and third-party systemintegrators These third-party firms include Accenture, Cap

Gemini/Ernst & Young, Bearing Point, and IBM Global

Services at the high end, as well as a long list of smaller

specialty firms.

Whats the difference between working with SAP and

working with a third party?

SAP has its own internal group of consultants who can give you

detailed support for your SAP NetWeaver (or any other SAP

product) implementation, regardless of your industry. By contrast, system integrators are companies that have formed

partnerships with SAP. They act as extensions of SAPs own

consulting team, filling in gaps or bringing in specialized

industry or technology expertise.

8/13/2019 12ASAP (2)

28/35

Teachers pet: S P education SAP offers a rich education and training curriculum.

The company employs professional trainers and provides

public training on SAP NetWeaver and its many products.

If you prefer to stay within the comfort of your office, SAP

also offers virtual training and eLearning over the Internet.

Most SAP customers use training in two ways.

First, the techies find out how to implement and then

customize SAP NetWeaver.

Second, the end users of the tools find out how to use SAP

NetWeaver solutions like pros.

8/13/2019 12ASAP (2)

29/35

SAP Custom Development If our implementation falls into this category which involve

quite a bit of custom programming, the next group of

people youre likely to meet is the SAP Custom

Development team.

This team gets called in, like a hi-tech S.W.A.T. team,

whenever special coding is needed.

If your other SAP consultants and account representatives

tell you that SAP lacks off-the-shelf software that can

handle a part of your project. If thatsthe case, SAP Custom

Development can be used to build custom soft- ware for

you.

8/13/2019 12ASAP (2)

30/35

Unexpected help:Colleagues and SAP customers

SAP NetWeaver customers especially those in yourindustry or function (such as marketing or sales) can

help you by answering these questions:

How long did it take them to install SAP NetWeaver?

How much did their installation cost? How did installation cost compare with original estimates?

What sort of return on investment are they achieving, and how

does that compare with their original estimates?

What challenges did they encounter along the way and howwould they recommend that you deal with those same

challenges?

Their answers to these questions and more provide you

with invaluable inside information.

8/13/2019 12ASAP (2)

31/35

Analyze this IT industry analyst firms are a reliable, generally unbiased

source for information about IT products, vendors, and

markets.

They can help you compare SAP products with those of

other vendors from price, functionality, and technology

standpoints. Leading analyst firms include Gartner,

Forrester, META Group, and IDC.

Many of these firms offer both research and consulting

services. That is, they can sell you reports that give you a

sense of SAPs marketplace, technologies, competitors, and

future direction. But they can also advise you on your own

SAP NetWeaver installation and implementation.

8/13/2019 12ASAP (2)

32/35

Eye-ess-vee (ISV, to you) Another useful member of the SAP NetWeaver ecosystem is

the independent software vendor (ISV).

These companies partner with SAP to offer industry-

specific and function-specific software. Essentially, they fill

in the SAP gaps for specific industries or business

processes.

You may find that SAP acts as a reseller of the ISVs

software. If thats the case, the ISV software is already

included in your SAP NetWeaver package.

8/13/2019 12ASAP (2)

33/35

So glad you came: SAP hosting Another option that SAP offers is whats known in the

industry as hosting.

This kind of hosting occurs when SAP runs your SAPNetWeaver system from its data centre.

In other words, SAP hosts your SAP NetWeaver software onits computers, which you in turn pay the company to runand maintain.

Itslike buying a data centre and data-centre staff in a box,saving you the overhead and headache of running yourown. If you work for a large corporation with one or more data centres

already in place, hosting probably isnt for you. But if yourcompany is small or medium-sized, itsan option to consider.

Calling Dr. : SAP Support When your SAP NetWeaver project is a go, you make the

acquaintance of a new team: SAP Support.

The SAP Support team works in two ways: Theyre proactive

and reactive.

Reactive means that in the unlikely event that you find a softwarebug or some other problem in your SAP NetWeaver system, you can

call SAP Support and they quickly make a fix or repair.

Proactive means that SAP Support ensures that your SAP

NetWeaver system runs at its optimal levels. A subset of SAP

Support, called SAP Safeguarding, checks your system, looking for

opportunities to optimize and improve it and eliminate risk from

your project.
