This is a legacy function which has been deprecated with version 3.0.

All features provided by this post function are now available in the Update or copy field values post function.


Target field

Select the field to be updated with the result of the formula.


The expression must return a number or date/time value.

Additional options

Choose one or both of the following options:

Write protection

Check the write protection option if you want to prevent a field to be updated, if it already has a value. If checked, only empty fields will be set.

Update issue immediately

Choose to update issues immediately if you want Jira to fire a separate "Issue updated" event for any field change.  This will also result in a dedicated issue history entry.

Conditional execution

You can optionally specify a logical expression to define the circumstances (or conditions) under which the post function should be executed.

The result of the logical expression must return a boolean value of either:

  • true → the post function will be executed
  • false → the post function will not be executed

Using the conditional operator, even complex or multi-layered conditions can be constructed.

Make sure to learn more about defining logical expressions and browse through the various examples here: Logical mode

Run as

Select which user will be used to execute this post function. By default this parameter is set to the current user. You can also use field codes to run the function as a dynamic user (e.g. current assignee).

Make sure that the user running the post function has all the relevant permissions to perform the actions defined in the configuration (e.g. "Update Issues")!

If you want to keep track the actions being performed automatically, we suggest to create a dedicated JWT account, granted all relevant permissions, and use it in the Run as parameter to identify which changes have been made with JWT.
