IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel 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).

IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel 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.
