  • SAP Overview
    SAP Overview What is SAP? SAP (Systems, Applications, Products in Data Processing), is headquartered in Walldorf, Germany. They provide business software designed to help companies execute and optimize business and IT strategies. SAP defines business software as comprising enterprise resource planning (ERP) and related applications such as supply chain management (SCM), customer relationship management (CRM), product life‐cycle management, and supplier relationship management (SRM).1 SAP currently has: • More than 51,000 employees in over 50 countries developing, marketing, and selling applications and services • 82,000 customers of all sizes across 25 industries and in over 120 countries • Listings on the Frankfurt and New York stock exchanges SAP operates in three geographic regions: EMEA (representing Europe, Middle East, and Africa), Americas, and Asia Pacific Japan (APJ, representing Japan, Australia, and parts of Asia). 2 History of SAP In 1972, SAP was founded by 5 former IBM employees in Mannheim, Germany with the vision to “to develop standard application software for real‐time business processing.” After the first year, they created the first financial accounting software application, which came to be known as the "R/1 system." "R" stands for real‐time data processing. By the end of the 1970s, R/1 evolved into SAP R/2. The programming language ABAP (Advanced Business Application Programming) was also a derivative of R/2, originally serving as the report language for the system.3 In the 1980s, SAP R/2 was updated to handle different languages and currencies‐‐subsequently, this lead to SAP’s international expansion into Austria, Denmark, Sweden, Italy, and the United States.

  • ABAP Development for SAP HANA? Your Comments and 1.2 Basic Principles of In-Memory Technology
    First-hand knowledge. Reading Sample As an ABAP developer you will want to use views and database procedures you created in SAP HANA Studio in ABAP. In this samp- le chapter, you will learn how to consistently transport native SAP HANA development objects, via the Change and Transport System “Integrating Native SAP HANA Development Objects with ABAP” Contents Index The Authors Hermann Gahm, Thorsten Schneider, Christiaan Swanepoel, Eric Wes- tenberger ABAB Development for SAP HANA 625 Pages, 2016, $79.95 ISBN 978-1-4932-1304-7 www.sap-press.com/3973 Chapter 5 ABAP developers want to use views and database procedures that they’ve created in SAP HANA Studio in ABAP. Developers are also used to a high-performance transport system and expect consistent transport of native SAP HANA development objects via the Change and Transport System. 5 Integrating Native SAP HANA Development Objects with ABAP Chapter 4 illustrated how you can create analytical models (views) and database procedures using SAP HANA Studio. Now we’ll explain how you can call these native SAP HANA objects from ABAP. We’ll also discuss how you can transport ABAP programs that use native SAP HANA objects consistently in your system landscape. 5.1 Integrating Analytic Views In the previous chapter, you learned how to model the different view types in SAP HANA Studio and how to access the results of a view using the Data Preview or Microsoft Excel. In Chapter 4, Section 4.4.4, we also explained how to address the generated column views via SQL. This section describes how to access the views from ABAP.

  • How to Develop in Abap
    HOW TO DEVELOP IN ABAP How to Develop in ABAP Applies to: SAP NetWeaver 7.0. For more information, visit the ABAP homepage. Summary This is the PDF version of the development blog series on SDN published in 2007 that gave an introduction to ABAP newbies who want to learn how to develop simple programs in ABAP. This PDF file does not contain the few blogs of the original series that explained how to install and administrate the ABAP demo version and how to import and export programs. This PDF document solely focuses on the many blogs that focused on development in ABAP. This is why the PDF file starts with blog 3 and has some gaps in the numbering. The main author of this blogs is Thomas Weiss but some blogs were written by other authors (Manfred Lutz, Hans Tillinger, Dirk Feeken). For more information read the original blogs. If you are interested in the comments and answers to the comments on the blogs you should read the original blogs on SDN. Otherwise this PDF file gives you an easy opportunity to work your way through the whole series. Author Bio Thomas Weiss has a Ph.D. in analytic philosophy. He worked as a professional writer before joining, in 2001, the SAP NetWeaver product management training team where his responsibilities included the e-Learning strategy for ABAP. After becoming more involved in writing ABAP material himself, he is now a member of the SAP NetWeaver Application Server Solution Management. One of his main interests lies in rolling out ABAP topics both for experts and for beginners by writing blogs in SDN.

  • Is COBOL Holding You Hostage with Math? | by Marianne Bellotti | Medium
    7/31/2020 Is COBOL holding you hostage with Math? | by Marianne Bellotti | Medium This is your last free story this month. Sign up and get an extra one for free. Is COBOL holding you hostage with Math? Marianne Bellotti Follow Jul 28, 2018 · 12 min read Face it: nobody likes fractions, not even computers. When we talk about COBOL the first question on everyone’s mind is always Why are we still using it in so many critical places? Banks are still running COBOL, close to 7% of the GDP is dependent on COBOL in the form of payments from the Centers for Medicare & Medicaid Services, The IRS famously still uses COBOL, airlines still use COBOL (Adam Fletcher dropped my favorite fun fact on this topic in his Systems We Love talk: the reservation number on your ticket used to be just a pointer), lots of critical infrastructure both in the private and public sector still runs on COBOL. Why? The traditional answer is deeply cynical. Organizations are lazy, incompetent, stupid. They are cheap: unwilling to invest the money needed upfront to rewrite the whole system in something modern. Overall we assume that the reason so much of civil society runs on COBOL is a combination of inertia and shortsightedness. And certainly there is a little truth there. Rewriting a mass of spaghetti code is no small task. It is expensive. It is difficult. And if the existing software seems to be working fine there might be little incentive to invest in the project. But back when I was working with the IRS the old COBOL developers used to tell me: “We tried to rewrite the code in Java and Java couldn’t do the calculations right.” This was a very strange concept to me.
