Automatically Pulling New Comments from Remote System
The Automatically pull new comments from Remote System is only available for Cases and Ideas mapping.
This setting is used to instruct the add-on to copy a Salesforce.com Case/Idea comments to JIRA Issue or not:
Enabled - all comments on the Case/Idea will copy and sync to JIRA Issue .
Disabled - no comments will copy to JIRA issue.
This setting applies when using create endpoint or synchronize endpoint from Salesforce.com for Case/Idea Objects or using Pull Changes in More > Manage Application Link from JIRA Issue.
Pulling Comments from Remote System
This setting allows you to control what comments are pulled from Salesforce.com to JIRA:
Private only - Only private comment will sync to JIRA issues
Public only - Only public comment will sync to JIRA issues
Regarding Comment Synchronization
Prior to version 5.3.6, all comments (whether public or private) were synchronized by default.
As a consequence, if you change the Pull comments from Remote System settings in this situation, all comments made prior to updating to version 5.3.6 will still be viewable.
Also, do take note that in situations where you have enabled the Public only option and synchronized your JIRA instance with Salesforce.com, and then changed the setting to Private only, all public comments will still be viewable.
Automatically push new comments for Issues associated with multiple remote objects
The Connector will automatically trigger the update to include every new comment made in a JIRA issue to a Salesforce.com Object.
This option is to control this scenario for JIRA Issues that are associated with multiple records of Salesforce.com Objects:
Enabled - all comments on the Case/Idea will push to Salesforce.com Case/Idea automatically.
Disabled - no comments will be pushed to Salesforce.com.
