A selection query is used to generate a random sample of cases and contains the selection criteria that is used to produce the random list of cases. Two types of selection query may be used. A dynamic query offers flexibility by allowing the audit coordinator to enter selection criteria such as case status and a case start date range, which is then used to produce a list of cases.
A fixed query provides a predefined set of selection criteria. If a fixed query is used to generate a random sample of cases within an audit plan, then no audit coordinator entry of selection criteria is required.
