Intro:
This article will cover Basics of HANA DB Authorization for initial learners, the in depth detailes will be covered in next Blog.SAP HANA
SAP HANA is an in-memory, column-oriented, relational database management system developed and marketed by SAP SE.
SAP HANA Security
Sap Hana Security is protecting important data from unauthorized access and ensures that the standards and compliance meet as per the security standard.
User Type in SAP HANA:
Depending on the different security policy there are two types of users in SAP HANA as below –
Technical User (DBA User) –
It is a user who directly work with SAP HANA database with necessary privileges. SAP HANA Database system provides following user by default as standard user–
- SYSTEM
- SYS
- _SYS_REPO
Database or Real User:
Database user is a real person who works on SAP HANA. There are two types of Database user as below –
Standard User: This user can create objects in an own schema and reads data in system views. Standard User created with “CREATE USER” statement. PUBLIC role is assigned for read system views.
Restricted User: Restricted User connects to database through HTTP Only. ODBC/JDBC access for client connection must be enabled with SQL statement.
User creation in SAP HANA-
only database user with ROLE ADMIN privileges can create user and role in SAP HANA
Step 1) To create new user in SAP HANA Studio go to security tab as shown below and follow the following steps;
Go to security node.
Select Users (Right Click) -> New User.
User Creation
Step 2) A user creation screen appears.
Enter User Name.
Enter Password for the user.
These are authentication mechanism, by default User name / password is used for authentication.
SAP HANA privileges:
Privilege is the permission to execute certain actions. Total 6 types of privileges are available in SAP HANA
1)System privileges
2)Object privileges
3)Analytic privileges
4)Package privileges
5)Application privileges
6)Privileges on User
1- System Privileges
It controls normal system activity. System Privileges are mainly used for
- Managing license
- Managing version
- Creating and Deleting Schema in SAP HANA Database
- Managing Audit
- Importing and Exporting content
- Managing user and role in SAP HANA Database
- Monitoring and tracing of SAP HANA database
- Performing data backups
- Maintaining Delivery Units
System Privilege
2- Object Privileges
Object Privileges are SQL privileges that are used to give authorization to read and modify database objects. Object privileges can be granted to catalog objects (table, view, etc.) or non-catalog objects (development objects).
Object Privilege
3- Analytic Privileges
Analytic Privileges are used to allow read access on data of SAP HANA Information model (attribute view, Analytic View, calculation View).
This privilege is evaluated during query processing.
Analytic Privileges grants different user access on different part of data in the Same information view based on user role.
Analytic Privileges are used in SAP HANA database to provide row level data Control for individual users to see the data is in the same view.
Analytical Privilege
4- Package Privileges
Package Privileges are used to provide authorization for actions on individual packages in SAP HANA Repository
Package Privilege
5- Application Privileges
Application Privileges are required in In SAP HANA Extended Application Services (SAP HANA XS) for access application.
Application Privilege
6- Privileges on User
It is an SQL Privileges, which can grant by the user on own user. ATTACH DEBUGGER is the only privilege that can be granted to a user.
Privileges on User

System Privileges for administrative and development task
Object Privileges for database objects
Analytic Privileges for SAP HANA Information View
Package Privileges on repository packages
Application Privileges for SAP HANA XS applications.
Privileges on the user (For Debugging of procedure).
