Procedure

  1. Navigate to a metadata element, in this example the Address table of the dbo schema in the Staging DW PDM database.
  2. Click the Trace Data Impact icon.

    The Overview tab of the data impact details page opens and presents a text based lineage overview of Address.

    For example, if you make changes to the Address table of the dbo schema in the Staging DW PDM database, these changes will impact the Dimensional DW PDM, Staging DW PDM and Vendor Mart databases. They will also impact all the sub-elements contained in these databases.

  3. Click the Details tab to open the detailed column level lineage report.

    The tables listed in the Lineage Feature column are sub-elements of the tables from the Origin Feature column.

    For example, if you make changes in the AddressDescription column, these changes will impact the Billing Address Description, Customer Payment Address Description and Shipping Address Description columns of the Customer PO Invoice Item table of the dbo schema in the Dimensional DW PDM database.

  4. Click the Graph tab to open a graphical report of the lineage.
