Go to Parameters/Variables tab, click on Input Parameter Manage Mapping and select Data sources. Click Auto Map By Name button to automatically copy input parameters from the Table Functions to the view. Now when previewing data on the view, there will be pop up with input parameters. Creating the partitions in advance and staying few steps ahead of your data can save you from a lot of stress and headaches. Here’s an example of how easy it is to implement a task that will automatically create partitions. Test Table Partitions. Let’s create a test table. Install and run AOMEI Partition Assistant, and choose “Partition Recovery Wizard” on the left top of the window. And choose the disk where your partition located, and click “Next”. To create a partitioned table for storing monthly reports. Step:1 First we will create database. Step:2 Give database name is PartitioningDB. Then click on ok button. Step:3 After creating database then open new query tab. Step:4 In new query we will create additional filegroups.
If you want to partition the table, you first need to create the file, filegroups and partionned table and set the partitionning manually Creation of N+1 partitions for 2015 Q1 (before, Q1 and after Q2) on a table with an int identity PK and a datetime2 partitioned column.

SAP HANA Lifecycle Management includes two features in HANA system: Platform Lifecycle Management for performing updates and customizing SAP HANA platform, and Application Lifecycle Management to manage applications based on SAP HANA system and transports.
SAP HANA Admin ─ Platform Lifecycle Management
SAP HANA Platform Lifecycle Manager can be used to perform installation and update of SAP HANA system, to configure additional components, post installation configuration, to add or remove hosts, to view system information, and to configure inter-service communication.
Following are the key features under SAP HANA Platform Lifecycle Manager −
- You can integrate your SAP HANA system with business solutions such as - SAP Solution Manager by registering under System Landscape Directory SLD.
- You can also add/remove hosts to your SAP HANA landscape.
- You can add and configure additional components, rename your HANA system or you can convert a single container system to multiple container system and vice versa as shown in the following screenshot.
In the above screenshot, you can see different options under SAP HANA Platform Lifecycle Management.
SAP HANA Platform Lifecycle Management can be accessed via three ways −
- Web User Interface
- Graphical User Interface
- Command Line
SAP HANA Admin ─ Application Lifecycle Management
You can use SAP HANA Application Lifecycle Management to support all the phases of lifecycle of SAP HANA application development, defining the application structure to perform transport and update management for Applications.
SAP HANA Application Lifecycle Manager supports various phases of application development −
- Model − Define Package structure, define package hierarchy, and assign packages to Delivery Units for application development.
- Develop − Perform application development in packages and to track changes.
- Transport − Transport your developed application and it can be done using transporting products or delivery units.
- Assemble − Assemble your developed product and translation delivery units for assembling your add-on product.
- Install − Install products and software components from SAP Support Portal.
Access SAP HANA Application Lifecycle Management (ALM)
To access SAP HANA ALM, you can open SAP HANA Cockpit and navigate to SAP HANA Application Lifecycle Management.
You can click HANA Application Lifecycle Management from here or can be opened directly using the web browser.
http://<WebServerHost>:80<SAPHANAinstance>/sap/hana/xs/lm
Example − In our system, HANA ALM is accessed using the link − https://hanaerp:4312/sap/hana/xs/lm/?page=HomeTab
In SAP HANA Cockpit, you can use tiles available in the SAP HANA Application Lifecycle Management and in the SAP HANA Application Installation and Update groups. These tiles can be customized as per your requirement.
SAP HANA Application Lifecycle Management Roles
In order to perform SAP HANA Application Lifecycle Management tasks, you should assign application lifecycle management roles to the users. There are various roles that are available in SAP HANA system to perform HALM tasks. Few of the key roles include −
sap.hana.xs.lm.roles::Administrator
This role is required to perform all read and write operations in the SAP HANA Application Lifecycle Management and to grant access privilege to other uses in SAP HALM environment.
sap.hana.xs.lm.roles::Developer
This role is required to perform changes and to work on the change list and add objects to the change list from the development perspective.
sap.hana.xs.lm.roles::ExecuteTransport
This role is required to perform specific transport operations but they can’t perform system register or maintain systems, define new transport routes, delivery units, or new packages in the repository.
These roles can be assigned to the users using SAP HANA Cockpit or under SAP HANA Studio → Security tab.
In the above screenshot, you can see different SAP HANA Application Lifecycle Management roles that can be assigned to the users for performing development and transport tasks.
We distinguish between two partitioning approaches: vertical and horizontal partitioning, whereas a combination of both approaches is also possible. Vertical partitioning refers to the rearranging of individual database columns. It is achieved by splitting columns of a database table into two or more column sets. Each of the column sets can be distributed on individual databases servers. This can also be used to build up database columns with different ordering to achieve better search performance while guaranteeing high-availability of data. Key to success of vertical partitioning is a thorough understanding of the application’s data access patterns. Attributes that are accessed in the same query should rely in the same partition since locating and joining additional partitions may degrade overall performance. In contrast, horizontal partitioning addresses large database tables and how to divide them into smaller pieces of data. As a result, each piece of the database table contains a subset of the complete data within the table. Splitting data into equivalent long horizontal partitions is used to support search operations and better scalability. For example, a scan of the request history results in a full table scan. Without any partitioning, a single thread needs to access all individual history entries and checks the selection predicate. When using a naïve round robin horizontal partitioning across 10 partitions, the total table scan can be performed in parallel by 10 simultaneously processing threads reducing response time to approx. one ninth compared to the single threaded full table scan.
