Copy to Jira
Gantt field values are only available in Gantt and Structure; however, it is possible to write Gantt values to Jira fields, using Copy to Jira. This way, these values can be viewed and utilized by anyone, whether they have access to Structure or not.
To copy Gantt values to Jira:
Select the Copy to Jira button in the Gantt toolbar.
Choose your From (Gantt field) and To (Jira field) values. Gantt Start Date and Finish Date are selected by default, but you can change these and/or add additional fields as necessary.
Select Start Copying.
