Derived rules are attribute and entity business rules that have been promoted to and are currently associated with reusable rules called library rules. A derived rule is like a link to a library rule, and you can edit whether the rule inherits certain settings from the library rule or whether the library rule inherits settings from the derived rule.
- See example:
-
A parent rule is considered the rule from which other rules inherit settings. For example, if you have a an EBR named Boston, and you promote Boston to the Library and create an association to the Library version of Boston (as opposed to copying the rule to the Library without an association), the version of Boston in the Library will be the parent rule. However, you can set settings in the derived version of Boston (the first, original rule) to override (supercede) the settings in the Library. By default, after a rule is promoted to the Library (with associations) it is a parent rule, until settings are overridden in the derived rule.
If you want to edit the expression elements (functions, attributes) of a library rule, do so from the Library tab. For more information, see Edit Library Rules.
To edit derived business rules
-
Select one or more of the following options:
- Override parent threshold. Supercedes the original passing threshold rows or values percentage for the library rule. When selected, enter a passing threshold value. For ABR rules, also select the rows or values threshold option.
- Override parent enabler. Supercedes the original enabled setting. When the parent library rule is enabled, the Enabled: check box displays a grayed-out check. When you check Override parent enabler:, the Enabled: check box becomes active, allowing you to check it and override the parent.
- Override parent index control. Supercedes the index type set in the original rule. When selected, choose the index type, either Normal (creates an index for failing rows, up to the default threshold (10,000 by default.) If the number of returned failing rows is higher than the default threshold, no index is created.), Unlimited (creates a full index for all failing rows), or Limited. If Limited, in the Index threshold field enter the maximum number of failing rows you want returned and indexed.
-
Override parent priority. Supercedes the business rule priority value set
in the original rule. When selected, click the Priority drop-down list to
select a different priority. To add or edit a priority, click the ellipsis button
(
) below the
Priority drop down. -
Override parent categories. Supercedes the business rule category selection
in the original rule. When selected, you can add or remove categories and
subcategories by clicking the ellipsis button ().
