18. ERP Technical Customization
Davenport:
Module Selection
Table Configuration
Code Modification
Brehm, et.al. :
Configuration
Bolt-on’s
Screen masks
(eg: 3 screens into 1)
Extended Reporting
Workflow Programming
User Exits
ERP Programming
(eg: ABAP/4)
Interface Development
Package Code Modification

19. Module Selection Implement one or more modules
Default configuration of the vendor
May be appropriate for small companies
Rarely sufficient for many companies

20. Configuration Configuration: Changing parameters in tables in SAP R/3
SAP promises that configuration specifications will transfer without problems to later versions of their software
SAP calls configuration customization

23. Defining Companies

24. Code Modification (Customization)
Customization: Changing code in SAP R/3.
Today such changes are done in a programming language developed by SAP called ABAP/4.
(In future it will also be possible in J2EE.)
May involve defining new database tables
It is possible to make changes to the code that SAP will not support.
Future upgrades will need to be re-customized (expensive).

25. Process Customization
Process Customization: The degree to which the business process is changed to fit the system.
Business process:
Tasks
Resources
Outcome
Relationships among tasks
Relationships among resources and tasks
IIMM Jamshedpur

26. Process Customization Categories
No change
Change in tasks and resources
No changes in relationships among task and configuration of resources
Eg: Task automation
Incremental change
Improvements in tasks and resources
Improvements in relationships among tasks
Improvements in relationships among tasks and resources.
Nature of process and outcome measures unchanged
Eg: Total Quality Management (TQM)

27. Process Customization Categories
Radical Change
Fundamental rethinking and radical redesign of elements in a business process including measures of performance
Eg: Business Process Reengineering
Eg: Move from functional view of organizations to process view of orgs.

31. Some Terminology
Basis Software. The R/3 Basis is similar to an operating system that specifically has the capability of processing any of the SAP R/3 transactions. It’s a middleware between the operating system and the servers that allow for smooth operations across different servers, operating systems, and databases.
ABAP: Advanced Business Application Programming (ABAP/4), is a special‑purpose, fourth generation language developed by SAP, is used to write programs for the specialized requirements of creating custom reports, screens, user‑defined functions, and special industry solutions for use with the SAP R/3 System.

32. What is SAP Netweaver?
A comprehensive integration and application platform, SAP NetWeaver works with your existing IT infrastructure to enable and manage change.
SAP NetWeaver embraces Internet standards such as
HTTP,
XML, and
Web services.
Ensuring openness and interoperability with Microsoft .NET and Java 2 Platform Enterprise Edition (J2EE) environments such as IBM WebSphere.
