Your client wants to minimize the validation rules that execute against a time card and only under certain circumstances they want certain validation…

Oracle Time and Labor lets you attach a time category to each row of a rule set. At run time the engine first checks the time card for entries that match the category; only if a match exists are the validation rules on that row executed and, if required, their messages displayed. Because rules whose category isn’t met are never invoked, this approach minimizes processing and satisfies the requirement that validations run only in specific circumstances.

A. Rule still launches for every time card; HR-data filter happens inside the rule, so processing isn’t minimized.

C. The rule always executes; parameter checking occurs after invocation, so no reduction in rule firing.

D. Embeds conditional logic inside the formula but the rule is invoked on every submission, defeating the stated goal.

1. Oracle Fusion Cloud Time and Labor Implementation Guide 24A, “Create and Assign Time Entry Rule Sets – Rule Set Rows and Time Categories,” p. 453–455: explains that rules on a row run only when the time card contains entries in the specified time category.

2. Oracle Fusion Cloud Time and Labor Implementation Guide 24A, “Improving Performance with Time Category Filtering,” p. 457: recommends category filters to avoid unnecessary rule execution.

3. Oracle Support Doc ID 2023462.1, “Best Practices for Configuring Time Entry Rules,” §2.3: confirms that category-based rule sets reduce validation overhead.
