How can I bulk update a "Script Field" custom field for old issues?

[Merve Nur Sevinç]

In Jira Cloud, a custom field created with Script Field does not calculate data for issues that were created before the custom field was added. How can I update this for all issues? I use this custom field to perform a calculation. It calculates and reflects the data in newly created tasks, but for older tasks, the field needs to be opened individually. Can this calculation be done in bulk?

What are you using to provide your "script field"?

Hi,

May be you could use a script in the console to update the field
