The Campaign Daily Budget is required to set an amount equal to or greater than the Ad Groups bit (or bid for Ad) in the Campaign. For this reason, when changing the Campaign Daily Budget, it is necessary to set an amount that is equal to or greater than the highest bid for any Ad Group (or Ad).
	
The Campaign start / end date in the schedule settings must be a date of the future.
Tips
 
	
Past date is not allowed for Start and End date for schedule setting.
	
You cannot edit the Start Date of campaigns that have started ad delivery on Search Ads. Please create a new campaign with new date.
