4. Create Universe in SAP HANA From earlier tutorials, we know that there are two ways in which the reporting tools can connect to SAP HANA. One way is a direct OLAP connection and another is an indirect relational connection. In the relational connection type, reporting tools fetch data from a universe layer instead of connecting directly to SAP HANA. Thus, SAP BusinessObjects Universe acts like a middle layer between reporting tools and SAP HANA. A universe contains data foundation layer which holds data tables with joins and conditions applied to them (much like information views). Business Reporting tools such as WebI, Crystal Reports for Enterprise and Dashboard designer use Universe as an intermediate layer to connect to SAP HANA. Although, in the current versions of Web Intelligence (WebI), the provision of connecting directly to SAP HANA has been introduced. 4 What is BusinessObjects Universe?

5. Benefits of Creating a Universe in SAP HANA 5 By using the universe layer to use data from SAP HANA, the user benefits in many ways: Offers higher output customization for business users. Can use query time prompts and variables. Data integration of data from HANA with data from other data sources by the virtue of embedded multisource technology. Enables data modeling in the Information Design Tool.

6. Steps to Create a Universe in SAP HANA using IDT Follow the steps given in this section to learn how to create a universe in the Information Design Tool (IDT) of SAP HANA. 6

7. 1. Connecting to SAP HANA 7 Step 1. On the Information Design Tool page, go to File and click on New and then click on Project. Step 2. Name the project (Project Name), suppose we name it Dtf_Demo_Connection. Then, click on Finish. All the resources required for universe development will store under this project. You can also change the location of this file from the Project Location column. Next, we need to establish a connection with SAP HANA. You can either make a relational connection (connecting to tables) or an OLAP connection (connecting to views). We have selected a relational connection.SAP HANA Step 3. To create a relational connection, right-click on the name of your project > New > Relational Connection. Step 4. Name the connection (Resource Name) and add a Description if you like. Click on Next>. Step 5. Select the HANA specific driver from the Database Middleware Driver Selectiondialog box. Click on Next> to continue.

8. 8 1. Connecting to SAP HANA Parameters for SAP HANA Database Connection Step 6. Enter the connection details like Authentication Mode, User Name, Password, Host Name, Instance Number, etc. Click on Next. Step 7. You can manipulate more connection settings in the next window such as Connection Pool Mode, Pool Timeout, Array Fetch Size, Array Bind Size, Login Timeout, JDBC Driver Properties. Then, click on Finish. Thus, the connection to SAP HANA will be successfully made. You can click on Test Connection to confirm the connection.

9. 2. Creating the Data Foundation 9 Step 8. In the Information Design Tool, right-click on the name of your connection (Dtf_Demo_Connection) and select New Data Foundation. Step 9. Name the data foundation (Resource Name). For the sake of understanding, we will name the data foundation “Dtf_Demo_DF”. Then click Finish. Step 10. Now, you get to see all the tables that exist in the HANA database under the Connection tab on IDT. You can select a node and expand it to see the tables within it. To add tables into the universe, drag and drop the tables in the Master area on the right. Join two tables by pulling the cursor between two fields of the tables that you wish to join. Step 11. You can edit the join properties by double-clicking on the join. You can set the join condition, create a shortcut join, outer join for the left or right table, view the expression and cardinality of the join. Step 12. Click on the save icons on the bar (on IDT main page) to save the newly created data foundation.

10. 3. Creating a Business Layer 10 Next step is to create a business layer on top of the data foundation we built. Step 13. Right-click on the name of the data foundation (Dtf_Demo_DF in our case) and selectNew Business Layer. Step 14. Then enter the name of the business layer. For instance, we give the name“Dtf_Demo_BL”. Click on Finish. This will fetch all the classes and objects based upon the tables we selected in the data foundation (in the Business Layer section). You can select an object and view the Name, Description, Field Type, Data Type, SQL Definition, Keys, Advanced Operations, Source Information, etc and edit them.

11. 3. Creating a Business Layer 11 You can also manipulate the SQL script using SQL assistant. This way our business layer is ready. Step 15. Now, before we save our business layer to BO repository, we need to secure our connection by publishing it on the repository. To publish the connection, right-click on the connection name (Dtf_Demo_Connection.cnx) and select Publish connection to a repository. Then, click on Finish. This will create a secure.cns (Dtf_Demo_Connection.cns) connection. Step 16. Next, we’ll change the connection of data foundation to the secure.cns connection. Step 17. Now, finally, we will publish our business layer to a repository. To do this, right-click on the name of your business layer (Dtf_Demo_BL) then select Publish and then click on To a Repository. You can check the integrity as you like. Click Next>. Step 18. Select the folder in which you want to store it. Click on Finish and your universe is published successfully.

12. Crystal Reports 12 SAP Crystal Reports is a windows-based tool used for creating reports for the purpose of printouts and publishing such as sales invoice, sales orders report, etc. In this tutorial, we will learn the process to directly connect SAP Crystal Reports with the SAP HANA database using appropriate drivers. Then, we will use the data in Crystal Reports to create our reports. SAP Crystal reports is popular because of its crystal clear and pixel perfect visuals. It uses JDBC/ODBC connectors and SQL as interaction language to connect to the SAP HANA database.SQL as interaction language

Step 11: Chart In the final step, you get to select from three standard chart types in which you wish to visualize the data. The available chart types are line chart, pie chart and bar chart. You can also go with No chart option. You also get to manage the chart from the options Chart title, On change of and Show summary. Click on Finish. Step 12: We finally have our report ready with the charts and tables we selected to be displayed. You can perform a range of manipulations and analytical operations on the dataset from the reporting interface. You can apply more advanced features and make different types of visualizations using the data.

19. Reporting in Microsoft Excel 19 As we know, SAP HANA is an efficient in-memory database technology which provides data to the users in the blink of an eye. On the other hand, MS Excel is one of the most widely used data representation, analysis and reporting software of all time. Excel’s capabilities are extended by connecting it to SAP HANA which provides real-time data access and ad-hoc analysis on billions of data rows. MS Excel offers HANA support from the 2003 version to the current version. Excel uses an OLAP connection to SAP HANA database and information layers which is a direct connection. The interaction language used is MDX and the connection driver required is ODBO driver.
