Now, let’s begin our tutorial on using SAP transaction RSA15.

What is SAP Transaction RSA15?

SAP Transaction RSA15 (Data Sources in BW) is a key transaction code used in SAP to manage data sources in the Business Warehouse (BW) module. It allows users to create, change, and display data sources, which are used to extract data from various source systems into the BW system. With RSA15, you can seamlessly manage the extraction of data, ensuring accurate and efficient data integration and analysis.

Step 1: Accessing SAP Transaction RSA15

To start using RSA15, follow these steps:

1. Log in to your SAP system using your user ID and password.
2. Launch the SAP Easy Access Menu.
3. Navigate to the “Business Explorer” folder and expand it.
4. Locate and click on the “Business Warehouse” folder.
5. From the sub-menu, select “Extraction” and click on “Data Sources” to proceed to the RSA15 transaction.

Step 2: Understanding RSA15 Transaction Screen

Once you have accessed RSA15, you will encounter the RSA15 transaction screen, which consists of various fields and tabs. Let’s explore each of them:

• Data Source Selection: This section allows you to search for existing data sources or create new ones.
• Data Source Details: Here, you can view and manage the details of a selected data source, such as its name, description, and extraction logic.
• Extraction Structure: This tab provides an overview of the extraction structure for the selected data source, including its fields and their mapping to source system data.
• Transfer Rules: The transfer rules tab displays the mapping between the data source fields and the corresponding BW InfoObjects.
• Update Rules: In this tab, you can define the update rules for the data source, specifying how the extracted data should be transformed and loaded into the BW system.
• Data Source Activation: The activation tab allows you to activate the data source, making it available for data extraction and loading.

Step 3: Creating a Data Source with RSA15

Creating a data source is a common operation performed using RSA15. It involves defining the extraction logic and mapping the source system data to the BW system. Here’s how you can create a data source using RSA15:

1. Start by selecting the “Create” button in the Data Source Selection section.
2. Enter a unique name and description for the data source.
3. Define the extraction structure by adding the necessary fields and their characteristics.
4. Map the fields of the extraction structure to the corresponding source system fields.
5. Define the transfer rules and update rules to transform and load the extracted data into the BW system.
6. Activate the data source to make it available for extraction and loading.

Congratulations! You have successfully created a data source using SAP transaction RSA15.

Step 4: Exploring Additional Functionality

SAP transaction RSA15 offers various additional functionalities to streamline your data source management processes. Here are some notable features you can leverage:

• Change Data Sources: RSA15 allows you to modify existing data sources. You can edit fields such as the extraction structure, transfer rules, update rules, and more. Simply select the desired data source and make the necessary changes.
• Display Data Sources: Use RSA15 to display existing data sources by entering search criteria such as the data source name or description. This allows you to review and analyze the details of the data sources in your BW system.
• Transport Data Sources: RSA15 supports the transportation of data sources between different BW systems. This feature enables you to easily move data sources across landscapes, ensuring consistency and efficiency in data integration.
• Data Source Activation: In addition to creating data sources, RSA15 also allows you to activate or deactivate existing data sources. Activation makes the data source available for extraction and loading, while deactivation suspends its usage temporarily.
