If you use both dayparting and status rules on the same ad groups, the dayparting rule may overwrite actions performed by the status rule.
The below image shows a status rule pausing a poor-performing ad group while dayparting keeps re-enabling it.

To use both status rules and dayparting:
- Ensure you have 1 campaign and 1 ad group structure.
- Add status rules to pause the campaign and ad group for a poor-performing ad group.
- Add status rules to enable the campaign but keep the ad group status unchanged. Refer to the preset rule "Resume Ads (With Day Parting)."
The algorithms will work like this:
- If an ad group stops performing, the status rule will pause the campaign and the ad group.
- Dayparting will not make any changes, as it does not act on paused campaigns for Sponsored Products.
- If an ad group with updated sales attribution causes ACOS to drop to a healthy level, another status rule will enable the campaign.
- In the following hours, when dayparting runs, it will enable the ad group if it falls within the active hours.
