Legacy: Control Rule Assignment 
Control Rule Assignment is done for specific initiatives. You assign rules to controls for automated testing and monitoring. Rules can be assigned to controls that have a test automation of either Automated or Semi-automated.
You can specify the testing frequency of a rule that has been assigned to a control. Set up the time intervals initially through the Customizing activities. You can assign multiple testing frequencies to a rule. You can choose any combination of annually, semiannually, quarterly, monthly, weekly or any.
Rule frequency can be specified for the two types of control testing:
Compliance – to test effectiveness of control for the purpose of reporting to your internal or external auditors.
Monitoring – to monitor continuous operating effectiveness of control. A control can be assigned multiple rules that may have different testing frequencies.
Example
A rule can have quarterly and monthly frequencies for compliance tests, and a weekly frequency for monitoring activities.
Prerequisites
Rules must be created and defined before performing the control rule assignment. For more information, see Creating Automated Test Rules.
