Overview of SAP HANA 2.0

In this blog post I want to elaborate and giving you an overview of SAP HANA 2.0.

Overview

Need for Digital Platform

The world is becoming the digital world, the world is now more connected and digital due to the extreme growth of mobile and tablets devices results the huge increase of data volume in every seconds and now the addition of “Intelligent” is much needed like never before. The “Intelligent” is that how we can get reward from any raw data smoothly. In today’s world the users needs instant response for their queries no matter how far the responsible person is. Data science is also available to businesses and every economic sector, this means machine learning and AI (Artificial Intelligence) is now displaying in every application due to this rapid and fruitful responses creating in every moment. New types of data is also available because of this the analysis on huge data has its high.

Load flat file decimal values to ADSO (SAP BI) and access in SAP HANA Cal view ( eclipse/H Studio)

We had a requirement to load GAS emission data into SAP BI, as the business does a lot of manual calculations in excel, to get the emission factor which is dependent on multiple values. They first need to sum up the values, do a standard deviations, SQRT of some NO2, Co2, IC4 values, divide it by some factor etc., which is a heavy excel based lookups and calcuations.

SAP S/4 HANA for Dummies

With the proliferation of digital transformation and all of its associated technologies such as RPA, cloud, AI etc. software vendors are swiftly adapting their current product offerings to meet the new wave of business demands. SAP, the behemoth in the ERP space is no exemption. SAP’s core ERP product has always been ECC but over the years the software giant has invested in developing an intelligent ERP system. This new system is not an upgrade to its core ECC but a complete new business suite with a simplified core, an in-memory database designed by SAP, a grade-A role based user experience called Fiori, and additional flexibility to integrate and extend intelligent solutions in the cloud with SAP S/4HANA cloud platform. It is called S/4 HANA. Each new version has a simplification list. Simply type **** (product version e.g. 1909) SAP S4HANA SIMPLIFICATION LIST online to get the information.

Adding XS Tooling to your SAP HANA, express edition Server Image

Out of the box the SAP HANA, express edition (HXE) server only option is ready to go with a lot of basic functionality. However, to use it you need to install the SAP HANA plugin for Eclipse. This of course is not a bad thing, however you may also like the idea of using the browser based tools.

This guide will help walk you through the steps necessary to install the SAP HANA XS tooling allowing you to use a browser to interact with your server going forward.

Lets discuss some good practices of coding

This blog will help folks who just on-boarded for ABAP in understanding the codes in line with it.

Note: 1st block of code indicates incorrect way of coding. Codes that follow the golden rules are written just after that.

Association Analysis Algorithms Implementation using HANA ML Python APIs.

Let’s Start –

Here is small list & introduction of the methods which I will be implementing one by one.

Introduction and algorithm description

I have used Jupyter Notebook which uses the real time itemset dataset to demonstrate the association rule mining algorithms below which are provided by in hana_ml package.

SAP Cloud Platform Extension Factory – Connecting to SAP Commerce Cloud

One of the key components of the SAP Cloud Platform Extension Factory Kyma runtime is the Application Connector.  The Application Connector provides a mechanism to simplify the connection between external systems and Kyma in a secure manner.  Once the initial connection has been established, the registration of the external Events and APIs of the external system takes place. The Events and APIs are then available within the Kyma Service Catalog.  The events can be consumed asynchronously with services and lambdas (serverless functions) deployed within Kyma.  Additionally, the Application Connector provides monitoring and tracing capabilities to facilitate operational aspects.

Currency Conversion in HANA based on Fiscal Period

Background

Whenever there is a requirement for Currency Conversion, the time reference plays a dominant role for determining exchange rates. Exchange rates vary on daily basis and which exchange rate should be applied for currency conversion is always a question.

Overview

In the past 3 parts of this series, we’ve done a lot of Cloud 9 configuration and coding. As someone whose first job is not that of a technical writer, I know that some steps may not have been clear. I also know as someone who follows along to tutorials, sometimes I just need a ‘fast forward’ or ‘catch up’ button. This will be the point of this part of the series. Or if you happen to massively mess up your progress, this will walk you through quickly getting back up and running as-of Part 3 in the series.

SAP HANA XSA Controller API Interaction

Since the introduction of SAP HANA extended application services, advanced model (XSA), SAP has supported many new approaches to accessing the platform APIs.  XSA is based upon Cloud Foundry which provides its core functionality via a command line client and a REST enabled web API.  XSA has this same functionality, but most of the focus on platform admin and interaction tends to focus on the CLI interface or the browser-based administrative UI which SAP deliveries. However behind that web UI are essentially calls to the controller APIs. These same APIs can be called from and used in your own applications.  In this blog I’d like to share some experiences trying to use these APIs.  There are some common challenges anyone using them will face and perhaps this blog can be helpful in that regard.
