Can anyone help me out in this issue please.

Answer 1

I would suggest that this be done in batch processes since it appears that you have a large list of data. If this is from a trigger, you may want to instantiate a queueables to call that batch only 1 time. To prevent recursion, set a static variable when it has been called to notify triggers in the same context that you've already done this. It will reset after the trigger context has expired. As of this posting, it is not fully available yet to track the job status without a custom poller to check the status.

Assuming this is being done in a job, if you created a field/object to track the jobs failures for reporting on the job, you could create a component to view the job results in a data table.
