Analyzing Metadata with the Metadata RepositoryLocate this document in the navigation structure

Use

You use the Metadata Repository as a central point of access to information about the metadata objects of SAP NetWeaver Business Warehouse. This metadata includes important object properties and their relationships with other objects.

Procedure

Metadata Display in the BW System

There are two different ways of displaying the metadata for an object:

  • In the Data Warehousing Workbench, under Modeling, you can display the metadata for the selected object by choosing Display Metadata in the context menu.
  • In the Data Warehousing Workbench, under Metadata Repository, perform the following steps:
    1. Choose the Metadata Repository function area in the Data Warehousing Workbench. A page appears with an overview of all BW metadata object types.
    2. Select the required object type. The system displays all the objects of the selected type.
    3. Click on the row with the required object.
      Note

      Choose (Find) to enter a text query and search for the metadata for specific objects.

      Note

      The data is displayed using the standard web browser. If you use the browser's search function (CTRL + F), only the results for the current HTML page are displayed.

The metadata repository prepares the metadata for an object as follows:

The system displays the following information in the Description area: type, technical name, description (short and long), object version, last changed by, last changed, Content version, Content change.

Under Documents, you can see the documents created for the object.

Under Objects in Environment, you can see the following tab pages:
