The policy types are listed as follows by priority from low to high: daily, weekly, and monthly. The following is an example. There are two resource configuration groups using the monthly and daily policies, respectively. Their application time ranges in a day overlap as follows: 04:00 to 07:00 and 06:00 to 08:00. In this case, the configuration of the group that uses the monthly policy prevails.</li><li id="admin_guide_000019__li27715561102226">If the repetition policy types of multiple resource configuration groups are the same, the time ranges of different dates can overlap. For example, if there are two weekly scheduling groups, you can set the same time range on different day for them, such as to 04:00 to 07:00, on Monday and Wednesday, respectively.</li></ul>
