SAP HANA Cookbook

Chapter 2. Data Provisioning

In this chapter, we will cover:

  • Loading data into SAP HANA – data provisioning methods
  • Uploading data from flat files
  • Using SLT to load data into SAP HANA
  • Using SAP Data Services as an ETL tool to load data into SAP HANA
  • Loading data into SAP HANA using DXC
  • Loading data using Sybase Replication Server

Introduction

The process of loading data into SAP HANA is called data provisioning. There are many ways to load data into the SAP HANA system. We can use several available tools for data provisioning. The decision to select an appropriate tool depends on the requirement and other factors, such as the type of source system, the complexity of data transformations required between the source system and SAP HANA, and whether the replication is real time or not.

In this chapter, we will see the different tools and options that are available for data provisioning: loading data from flat files, using SAP Data Services, SAP Landscape Transformation, and Sybase Replication techniques.

Loading data into SAP HANA – data provisioning methods

Based on the requirements, the data provisioning methods for loading data into SAP HANA are different. This recipe briefs you on the tools available for data provisioning and how they work.

Getting ready

This recipe briefs you on the tools available for data provisioning and its application.

How to do it…

The process of data loading is different for the data provisioning tools. In this recipe, we will see in detail the technique and options available for loading data into SAP HANA using different tools. The next recipes deal individually with each tool.

How it works…

As mentioned earlier, the selection of a data provisioning tool depends on the characteristics of the source system and other factors. The mechanism of each data provision technique differs. Let us look at the key factors in each technique that will help in deciding which mechanism to select. Here, the key factors will only be discussed for SLT, SAP DS, and...

Uploading data from flat files

Having learned about SAP HANA, its components, and its architecture, let's begin loading data into SAP HANA now. In this recipe, we will see how to load data from flat files.

Getting ready

To load data into SAP HANA from flat files, we will require the files in the form of a CSV or an Excel file (Office 1997 or above) saved in the client machine where we use SAP HANA Studio.

How to do it…

Let's load data into SAP HANA from an Excel sheet in three simple steps.

Step 1 – creating a table in the SAP HANA system

Initially, we create a table in the SAP HANA system. Then, we load the data to the newly created table. A table can be created either using SQL Console by writing a SQL code, or by using the graphical interface. We will see both the cases, as follows:

  • Using SQL Console: From Quick Launch, select SQL Console. This will launch SQL Console. Write the following code and execute it to create a table. On successful execution, a message will...

Using SLT to load data into SAP HANA

SLT stands for SAP Landscape Transformation. We use this technique for real-time replication of the data from source systems—SAP/non-SAP. This method is primarily used for replication from SAP source systems. Apart from real-time replication, we can also use SLT for batch mode loads as well. When the required landscape contains both real-time and batch mode, SLT is the best. This recipe shows us how to load data into SAP HANA using SLT.

Getting ready

In order to load data using SLT, we must first ensure that real-time data loading is required. Also, the exact number of tables that have to be replicated should be known before going for SLT; replicating unnecessary tables involves a higher cost.

How to do it…

We will now see the steps to configure SLT and replicate data in SAP HANA.

SLT configuration – creating a connection

Connections can be created from transaction LTR in the SLT system. This t-code is a browser-based application. Hence...

Using SAP Data Services as an ETL tool to load data into SAP HANA

We use SAP Data Services to load data into SAP HANA when there are high transformations to be applied before loading. When the scheduled data load is enough, real-time data loading is not required. We can also make use of DS with a real-time mechanism when non-SAP sources are included. In this recipe, we will see the steps to load data using SAP DS to SAP HANA.

Getting ready

To load data using SAP DS, we need a minimum of SAP DS Version 4.0 or higher and SAP HANA installed.

How to do it…

Of the four ways mentioned to create tables, we have already seen the first two ways using SAP HANA Studio, that is, GUI and SQL Console in the Uploading data from flat files recipe.

Now we will see how to create tables using the import of metadata option from SAP DS.

Creating table in SAP HANA using the import of metadata option

This can be done in four simple steps.

Step 1 – Creating a datastore for the source system in SAP Data Services...

Needed a quick read to round out my understanding of Hana. I wasn't expecting a whole lot when I downloaded this book. Turned out to be thorough while being fairly compact. I especially liked the links they embedded to related videos and documents.

I was a little disappointed in this book; it's overpriced for what it delivers. I'd like more depth to the examples (or pointers to online supporting documents) and more background on the setup of HANA.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
