Create a Comparison Rule

You use the Comparison Rules (SP) application to create comparison rules that you can add to a reconciliation task. You can create comparison rule records from the List tab or from the Comparison Rule tab in the application. A comparison rule defines how to compare objects or attributes of a child or parent object in one data set with a child or parent in another data set when the system executes a reconciliation task.

You can associate a comparison rule with a specific customer. You can then apply the comparison rule only to reconciliation tasks that are created for that customer. If you do not specify a customer, you can apply the comparison rule only to reconciliation tasks that are not associated with customers.

If you use Change and Configuration Management Database (CCMDB), you can create a full configuration item (CI) comparison rule that lets you compare CI relationships. For more information about creating full CI comparison rules, see Create a Full CI Comparison Rule.

To create a comparison rule:

1. On the toolbar in the Comparison Rules (SP) application, click New Comparison Rule . The application displays a new comparison rules record on the Comparison Rules tab.

2. In the Comparison field, enter the name that you want to assign to the comparison rule. This name is the unique identifier of the comparison rule.

3. If appropriate, in the description field, enter a brief description of the comparison rule. To enter additional information, click Long Description .

4. Optional: In the Customer field, specify the customer associated with this comparison rule.

5. In the Type of Reconciliation section, in the Data Set 1 field, click Select Value to select the appropriate data set. The application automatically populates the Data Set 2 field with the corresponding data set.  For example, if you select ASSET for Data Set 1, the application displays DEPLOYED ASSET for Data Set 2.

6. Select one of the following options:

7. To create a Data Set 1  filter, see Create a Data Set 1 Filter.

8. To create a Data Set 2 filter, see Create a Data Set 2 Filter.

9. To create a matches found definition, see Create a Matches Found Clause.

10. To create an attributes equality definition, see Create an Attributes Equality Clause.

6. When you complete all components of the comparison rule, click Save Comparison Rule  to save the comparison rule.
