Trying to create a Trigger to clear a field on the First of every month

Hi Community,

I'm an admin who is trying to create a Trigger (my first) that will automatically clear a checkbox field on the first of every month. Any help on this would be very grateful. 

Thanks,
Tara

  Hi Tara , 
If I understood correctly, you need to clear the check box first of every month no matter whether user edits the record or not. For this requirement, you need to use batch apex or scheduler apex or queueable apex jobs. 

Please refer this links

you can create a apex class that is scheduleable and call it once with appropriate time expression like '0 0 0 * * *' which triggeres your class where you should implement your apex code within a method i.e "global void execute(SchedulableContext SC)" to clear a field of your object.
Refer :https://developer.salesforce.com/docs/atlas.en-us.212.0.apexcode.meta/apexcode/apex_scheduler.htm

Please mark as best answer if you feel so.

Hi Tara,

For your requirements, Batch Class is the best solution Create a Batch Class it's scheduler class and then schedule it to run for every 1st from the schedule wizard provided by the salesforce
