Overwrite / append / prepend

For text fields and other fields that can accept multiple values (like checkboxes), you can overwrite, append, or prepend the new value to any existing value. For a text field, you can also choose a separator between the values (not shown in the screenshot above).

Create version if necessary

Imagine your origin issue has a version that you want to copy to the linked issue. If the destination field is Fix Version/s, Affects Version/s, or some custom field of type version picker, you can define that a new version will be created in the target project if it does not yet exist. If you don't choose this option and that version does not exist, the user receives an error message and the transition completes.

Create component if necessary

Imagine your origin issue has a component that you want to copy to the linked issue. If the destination field is Components, you define that a new component is created in the target project, if it does not yet exist. If you don't choose this option and that component does not yet exist, the user receives an error message and the transition completes.

Special sources

In addition to fields, you can select from the following special sources to copy to a destination issue. For example, you can copy the value of the previous user to the Assignee field of a new issue.

• *** empty ***: The destination field will be cleared.

• *** last comment ***: The last comment from the source issue will be copied. In some cases that might be the comment from the transition screen, which the user just entered while performing the current transition.

• *** transition comment ***: The comment that the user entered on the transition screen will be copied to the destination field.

• *** current user ***: The user who triggered the post function will be copied to the destination field.

• *** previous user ***: The field is updated with the previous user assigned to the destination field. This is valid for single-user picker fields.

• *** current datetime ***: The current date and time will be copied to the destination field.

Special destinations

• *** new comment *** : A new comment will be created with the copied value. When you choose to overwrite to new comment, a new comment is created, enabling you to add multiple comments in one post function.
  Examples:
  Copy Description to New Comment, overwrite → creates a new comment with the description.
  Copy Summary to New Comment, append with separator ", " → appends the summary to the previously created comment, so the comment will look like <Description>, <Summary>.
  Copy Assignee to New Comment, overwrite → creates a new comment.
  This configuration will result in two comments being created: one with the description and summary, and one with the assignee.
