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).

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 IST 600 ERP Systems: Key Implementation Issues U.

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.

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.
