The abbreviation HANA stands for "High Performance Analytic Appliance". From the very beginning, SAP's development of SAP HANA was focused on a product that could perform analyses at high speed. SAP HANA also combines hardware and software ("appliance").
Native HANA means it is something build on top of the HANA BOX and it can have the full HANA performance and benifits and there is another term called non-native HANA applications which means the developments done using other technologies can also run on top of HANA, like . net, java applications.
SAP HANA Table-level Optimization
- Use the appropriate table type based on the usage.
- Avoid using indexes on non-unique columns.
- Get better performance by assigning range, hash, and round-robin partitions to the large tables since the amount of data brought into working memory can be limited.
A referential join is also an inner join but it assumes that the referential integrity is maintained. This means if the columns from the right table, say, are not asked in the query then the join will not be executed and it gives all the rows from the left. Thus, it is an ommisible join.

An SAP HANA view is used to select data, analyze data, or perform calculations with data from the SAP HANA database. SAP HANA views are modeled in SAP HANA Studio for the SAP HANA database. There are various different types of view: attribute views, analytic views and calculation views.

The trial includes SAP HANA, express edition, available for free for development and productive use for up to 32 GB of RAM.
Implementation of the S/4 HANA is an overwhelming process and many-a-times it has failed miserably, some even ending in multi-million dollar lawsuits. Today, we will be looking at the top 5 monumental S/4 HANA failures that will definitely go down in history as epic ERP implementation failures of all times.
SAP S/4HANA is an ERP business suite based on the SAP HANA in-memory database that allows companies to perform transactions and analyze business data in real-time.
SAP HANA can integrate your data from both internal and external sources seamlessly. However, as we all know, SAP®'s newest ERP, S/4HANA®, only runs on a HANA database. So, if you are not currently using HANA and want to upgrade your SAP ERP to S/4HANA, you have to migrate the entire database as well.
The Systems, Applications &Products implementation which is popularly known as SAP is an application thatis designed to run an SAP HANA database. SAP HANA, on the other hand, is an in-memory database. In short, SAP is the platform for the SAP HANA database to run.
Not every IT Person knows programming and it not required to know programming. Typically in a SAP Implementations 90% are business people and 10 % person are developer who code in the system. The job you will be trained is going to be SAP System Administration which does not involve coding. It involves system analysis.
What are the key features of SAP S/4HANA?
- Smaller total data footprint.
- Higher throughput.
- Faster analytics and reporting.
- ERP, CRM, SRM, SCM, PLM co-deployed.
- Unlimited workload capacity.
- SAP HANA multi-tenancy.
- All data: social, text, geo, graph, processing.
- New SAP Fiori UX for any device (mobile, desktop, tablet)
SAP HANA offers a robust set of capabilities, including database management, database administration, data security, multi-model processing, application development, and data virtualization.
In SAP HANA Modeler perspective, you have an option of “Mass Copy” using which you can copy mass objects from package to other package. You have to define source and target package mapping. To add new package mapping, you can use <click to add> button and select Source and Target package from drop down list.
Goto the Tcode SE03 and select the option "change object directory entry" and execute. You will get a list of standard ABAP objects. Now select an empty row and give "R3TR" and "FORM" and give your SAP script name in the text box and execute. Here you can change the Package or Development class.
In the developer mode import dialog, you can browse the system to select the folder containing the object of interest. Next, you can add the desired database object from the selected folder. Select a package (from Objects for Import section) and click on Add button to import it into SAP HANA system.
In ABAP Development Tools (ADT), packages form the basic modules of ABAP projects. They are displayed as ABAP repository tree in the Project Explorer. Each package node can contain subpackages or development objects as subnodes. The package hierarchy is represented as a node tree.
In SAP HANA Studio, Content folder contains all the design time repository objects. In this folder, all objects created in HANA system are managed under packages. To create a new object, you have to first select a Package. Each of the object type is managed in different folder in a package.
Procedure
- Open SAP HANA studio.
- Open the SAP HANA Development perspective.
- In the Systems view, click [+] Add System and choose Add System.
- Type the details of the SAP HANA system in the following fields: Host Name:
- Select Next.
- Enter a user name and password for the connection, and select Finish.
The Content represents the design-time repository which holds all information of data models created with the Modeler. Physically these models are stored in database tables which are also visible under Catalog. The Contents node just provides a different view on the same physical data.
Another way is through SAP HANA Studio. In the landscape tab, under services, you will find the SQL port column. In this too, you need to open system DB in a studio if you want SQL port for system DB and tenant DB for its port.
It is the set of SAP HANA system components that are installed on one host. A single-host system contains one instance on the one host. Every system has an instance number , which is a two-digit identifier. Each instance in a multiple-host system must have the same instance number.
To open SAP HANA Cockpit via a web browser, you need to have browser support SAPUI5 library sap. m. You can also open SAP HANA Cockpit via HANA Studio. Navigate on HANA system → Configuration and Monitoring → Open SAP HANA Cockpit.
Procedure
- Open a Terminal and navigate to the following directory: /Applications/sap/
- Start the SAP HANA studio application: open -a hdbstudio.app Note. If you start the SAP HANA studio in a terminal you can add command line options (for example to set the SAP HANA studio workspace or to start an immediate system logon).
In the top-right corner of SAP HANA Studio, we have an option to open the available perspectives and change them. By clicking on the icon, we can navigate between perspectives.
During the tutorial, you use tools provided in the SAP HANA studio to perform the following tasks:
- Connect to an SAP HANA system.
- Create a repository workspace.
- Create and share a project.
- Write server-side JavaScript code.
- Display data.
