What is SAP Transaction RSDMWB?

SAP Transaction RSDMWB is a transaction code primarily used in SAP BW for managing data sources. RSDMWB allows users to create, modify, and delete data sources, which are essential components of BW data modeling. With RSDMWB, you can efficiently manage the extraction, transformation, and loading of data into your BW system, ensuring accurate and reliable reporting and analysis.

Step 1: Accessing SAP Transaction RSDMWB

To begin using RSDMWB, follow these steps:

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

Step 2: Understanding RSDMWB Transaction Screen

Once you have accessed RSDMWB, you will be presented with the RSDMWB transaction screen, featuring various tabs and fields. Let’s explore each of them:

  • Data Source Overview: This tab provides an overview of all existing data sources in your BW system. You can search, filter, and sort the data sources based on different criteria.
  • Create Data Source: In this tab, you can create new data sources by specifying relevant details such as the source system, source object, and extraction settings.
  • Change Data Source: Use this tab to modify existing data sources. You can edit various attributes, such as extraction settings, source system mapping, and field assignments.
  • Delete Data Source: Here, you can delete unnecessary data sources from your BW system. Be cautious when using this functionality, as it permanently removes the data source and its associated data.
  • Activate Data Source: The activation tab allows you to activate data sources after creation or modification. Activation ensures that the data source is ready for use in data modeling and reporting.

Step 3: Creating a Data Source with RSDMWB

Creating a data source is a fundamental task performed using RSDMWB. Here’s a step-by-step guide on how to create a data source:

  1. Start by navigating to the “Create Data Source” tab.

  3. Define the field assignments, mapping the fields from the source object to the data source.
  4. Configure any additional extraction settings, such as filters or delta settings, as per your requirements.
  5. Once you have entered all the necessary information, click on the “Save” button to create the data source.

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

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

  • Change Data Source: RSDMWB allows you to modify existing data sources by accessing the “Change Data Source” tab. You can edit extraction settings, field assignments, or any other relevant attributes.
  • Delete Data Source: If a data source is no longer needed, you can use the “Delete Data Source” tab to remove it from your BW system. Be cautious, as this action permanently deletes the data source and its associated data.
