Date fields mapping

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 this from Project Board Settings or from App Settings.
From TeamBoard within the project, click the settings cog on the right to go to Board Settings → Field Settings.
Turn on the option 'Map dates with Jira fields' and select the Jira fields you want to map to the Start date and End date.
Depending on your project's Screen Scheme, the issue types in the project may not have the fields you've selected. This list displays the current statuses. Issue types that don't have the required fields won't function properly, so you should add these 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 in App’s data to Jira fields ( this is a way migration from App to Jira )

After configuring correctly, issues in the project will use Jira fields when planning with ProScheduler
