Define the Match Criteria

The Match Criteria page lets you define a comparison between attributes of your source and target.

Follow these steps:

Note: Page fields marked with an asterisk (*) are required.

1. Select a source attribute, comparison type, and target attribute from the drop-down lists as follows:

   'Source_CI' Attribute

   Defines the USM attribute of the source CI that must have some relation to a target CI attribute

   Comparison Type

   Defines how the specified source and target CI attributes must relate. The options in this drop-down list change based on the data type of the selected attributes.

   'Target_CI' Attribute

   Defines the USM attribute of the target CI that must have some relation to a source CI attribute.

   Note: For USM property definitions, see the USM Schema Documentation that is provided on the CA SOI Bookshelf.

2. Click Add.

   The criteria are added to the expression, which appears in the logic tree and as an expression in the field at the bottom of the page.

   Note: If you define criteria that conflict with the potential values of the selected attributes (for example, if you select Equal To for two enumerated properties that do not share values), an error message opens.

3. (Optional) Repeat Steps 1 - 3 to add additional conditions and logic.

   Note: For more information about using advanced logic with multiple match criteria, click the Hints link.
