I get this error while trying to perform deletion using a batch job. I have all access to the object. In my case, Custom obj A is parent and B is the child (One to many). As per the code, when record of obj A is deleted, B obj related records should be deleted. Now, since the scheduled job runs only on Saturday, few of the child records won't exist in the system by the time the job executes the code. This is leading to the issue since the job is trying to record child records that don't exist in the system. How do i solve this?
