From Cloud 1.4.23 version and Server/DC 4.0.0 version TeamBoard Proscheduler supports mapping Start date and End date to Jira fields. Each project in Jira has different Screen Scheme with different Fields therefore you need to configure the field mapping at project scope. For program/portfolio boards which include multiple projects you may want to configure for all projects in the portfolio.
Please keep in mind that when mapping date fields to Jira fields the app follows Jira’s spec and some advanced feature such as scheduling task multiple times or planning 1 task for many users are not supported.
You can configure from Project Board Setting or from App settings
Project Board Settings
From teamboard in project click the setting cog on the right to got to Board Settings → Fields Settings
Turn on the option “Map dates with Jira fields” and select the Jira fields you want to map to Start date and End date.
Depend on your project Screen Scheme the issue types in project may not have the fields you picked, this list shows a current statuses. The issue types which don’t have the fields won’t work properly, you should add the fields to the Screen of those issue types
Click Save to save the settings, after saving you can migrate the existing start dates and end dates exists in App’s data to Jira fields ( this is one way migration from App to Jira )
After configuring correctly, issues in the project will use Jira fields when planning with ProScheduler
In App Settings
You can also configure the fields mapping for each project from App Settings
From Jira go to Apps → TeamBoard ProScheduler → Settings → Fields Settings
Select the project you want to configure in the dropdown list, then the same configuration with project board settings appears and you can map the fields
