You can retrieve details about artifacts, such as their total estimate value and time spent values from a work item, by using the XPathValueFetcher business rule. The XPathValueFetcher business rule queries artifacts in the Rational solution for Collaborative Lifecycle Management (CLM) application .
To configure an attribute to fetch artifact information from the CLM application
1 Click the Settings icon and then, from the Configure group, click Attributes.
2 Select the module that contains the Integration link attribute and that requires an attribute to fetch more information from the CLM system.
3 Click Add Attribute.
4 Select the attribute type based on the type of value that you fetch from the CLM application. For example, to fetch values from the estimate field in the Change and Configuration Management application, you can use integer attribute type.
Ensure that the attribute is editable.
5 Specify a name and description for the attribute.
6 In the Default value field, specify the XPathValueFetcher business rule in this format:
=XPathValueFetcher('Integration link attribute',"URL parameters","XPath expression")
