First of all check and confirm that the properties of the required repositories have had the Force Simple Management option set to True, and the Next Repository option is set to the repository as per the intended rule.

Select the Simple Management tab above the Inventory window to the right of the Customer tree view. Right-click and select Add.

This will open the Edit New Simple Management Rule window and display the Identity tab. On this tab enter an appropriate description into the Description field. In this example 'Return 2nd Last Day' has been entered.
