Custom field auto update value when another custom field updated before

[nhungttt148]

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

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.

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

@nhungttt148, 

This is not possible using OOB functionality. Do you have any plugins such as ScriptRunner for Jira or Automation for Jira installed?

Thanks,

Kian
