To build a table in SAP Data Warehouse, you would typically follow these steps:
Launch SAP Data Warehouse Management Console: Access the SAP Data Warehouse Management Console, which is the web-based interface used to manage objects in the data warehouse.
Create a Data Model (Optional): If you want to build the table within a specific data model, you can create the data model first. A data model acts as a container for related tables, views, and other objects. Skip this step if you already have a suitable data model.
Navigate to Data Builder: In the SAP Data Warehouse Management Console, go to the "Data Builder" section. This is where you can create and manage data objects like tables and views.
Create a New Table: Inside the Data Builder, locate the data model or folder where you want to create the table. Right-click on the folder, select "New," and then choose "Table" from the options.
Define Table Properties: A new window will appear, prompting you to define the properties of the table. You'll need to specify the following:a. Technical Name: The technical name of the table, which will be used internally in the system. b. Description: A brief description of the table's purpose. c. Package: The package in which the table will be saved. It helps with transport and organizing objects. d. Delivery Class: Determines how the table data will be transported between systems. e. Data Class: Specifies where the table data will be stored (e.g., hot storage or cold storage). f. Size Category: Defines the expected size of the table to optimize storage.
Define Table Structure: In the "Columns" section of the table creation window, define the structure of the table by adding the necessary columns. Each column should have a name, data type, length, and other relevant attributes.
Define Primary Key and Indexes (Optional): If needed, you can define a primary key for the table to ensure data uniqueness. Additionally, you can create indexes on specific columns to speed up data retrieval.
Save and Activate the Table: Once you have defined the table's properties and structure, save the table. Before the table becomes fully operational, you need to activate it. Activating the table generates the underlying database objects and makes it usable.
Transport the Table (Optional): If you are working in a system landscape with multiple environments (e.g., development, testing, production), you might need to transport the table to different systems using the SAP Transport Management System.
