I am not able to find assign using active assignment rule for Product Support case. I tried with clicking on Active box for Standard escalation case but still not working.

Hi @Dhara Kaji

To resolve the issue of

1. Check Assignment Rule Setup:
   • Go to Setup → Case Assignment Rules.
   • Ensure there is an Active assignment rule for Product Support cases (not just the Standard Escalation case).
   • If no rule exists, create a new Case Assignment Rule and add criteria for Product Support cases.
2. Verify Case Page Layout:
   • Go to Setup → Object Manager → Case → Page Layouts.
   • Ensure the "Assign using active assignment rules" checkbox is added to the layout.
3. Enable Assignment Rule Checkbox on Case Creation:
   • When creating a new case, make sure the "Assign using active assignment rule" checkbox is checked before saving.
4. Test by Creating a Case:
   • Create a new Product Support case and check if it gets assigned automatically based on the rule.

If the option still doesn't appear, try clearing cache, switching browsers, or checking user permissions.
