Hi Udupi,
Event 02 will not be useful in your case, because that might be effected after saving data in the table. So, that time and date may not be updated.
You try events 05 Creating a new entry or
18 After checking whether the data has changed.
As per the functionality, Event 05 is similar to 01, but I believe this may be helpful. So try.
One of these may helpful.
Thanks & Regards.
