If you want discussions to automatically be escalated into Salesforce as cases, create a policy to determine the conditions when this should happen.
Auto-escalation from Jive can occur whenever discussions are created and marked as questions. If you enable auto-escalation, you can choose to automatically escalate every question, or escalate questions only when they do not receive an answer after a specified time elapses. Your auto-escalation policy applies to all places (groups and spaces) in Jive by default. However, community administrators and users with owner or administrator rights to a group or space can override the setting for specific spaces by modifying the CRM settings for a space: see Creating a Place-Specific Escalation Policy. You'll see a list of places that currently have exceptions to the auto-escalation policy at the bottom of the Case Escalation dialog.
If you don't want auto-escalation to happen anywhere in your community, select Do not apply auto-escalation to any places. Users with permissions for manual escalation will still be able to escalate cases.
