Lineage provides details about data in a report, such as the data source and calculation expressions. You can access lineage information in Cognos Viewer, Report Studio, Query Studio, and Analysis Studio.
You can configure the default IBM Cognos 8 lineage solution, the IBM Metadata Workbench lineage tool, or a custom lineage solution. To use the default solution or IBM Metadata Workbench, ensure that the value for the Metadata Information Service URI parameter of the Environment category is configured as specified in the steps in this section.
To implement a custom lineage solution, you must
create a Web interface that translates the IBM Cognos 8 lineage request parameters and invokes the custom lineage solution.
For more information, see the section about integrating a custom lineage solution in the SDK Developer Guide.
change the value for the Metadata Information Service URI parameter of the Environment category to the URL of your lineage server.
To enable lineage, you must set up the Lineage capability. For more information, see Secured Functions and Features, and Object Capabilities.
In IBM Cognos Connection, click Launch, IBM Cognos Administration.
On the Status tab, click System.
Click the arrow next to System to display the Actions menu, and then click Set Properties.
Click the Settings tab.
For the Environment category, Metadata Information Service URI, type one of the following values.
If you want to configure the default IBM Cognos 8 lineage solution, type /lineageUIService.
If this value is already specified, click Cancel at the bottom of the page. You do not need to change anything.
If you want to configure IBM Metadata Workbench as your lineage solution, type
/lineageUIService?iis=http://workbench_server_name:9080/workbench/autoLoad.do
where http://workbench_server_name:9080/workbench/autoLoad.do is the URL where IBM Metadata Workbench can be accessed on the network.
workbench_server_name represents the server name where IBM Metadata Workbench is installed.
If you want to configure a custom lineage solution, replace the existing value with the URI that represents your lineage Web interface.
For example, type http://mycompany.com/ourLineageService.cgi
Click OK.
