How to clear a system field eg: in log work date started

[Mohanbabu Somasundaram]

Need to clear date started field. if user click on log work the system field date started should be cleared.

You will need an automation or scripting app to provide a listener function that can spot the log-work event and clear out your custom "date started" field (it's not a system field, Jira doesn't have a date started field built in)

Hi Nic 

Thanks for your update, do you able to provide me a sample script for this scenario, I have script runner addon to implement this.

https://library.adaptavist.com/entity/change-the-value-of-a-custom-field-in-a-post-function is a good start.  It sets a text field to some text, but you can just set your "date started" to null to blank it out.
