Custom field auto update value when another custom field updated before

Question

Hi guy,

I have 2 custom fields, like A and B

I need to set a custom field value for A that is the current DateTime when I updated the field value for B

Could someone please assist me in the config this request?

Before that, I configured a case that set a custom field value when transitioning (with post functions), but Idk how to set the above case.

Thank you so much

What smart value do you use to say when field value changed for B, updated Field A with current date time?

Thanks for your support @Kian Stack Mumo Systems @Tansu Akdeniz

I did it by Automation  with the scenario "When field value changed for B, update Field A with current date time"

Hi @nhungttt148

Welcome to the community.

Do you have any add-on? Ex;

* If you have Automation for Jira, you can simply configure this scenario. 
(When field value changed for B, update Field A with current date time)
* Or via Script Runner, you can add custom listener. When issue is updated, custom script looks for a change in field and update the other.
