Create a do nothing rule when manually selected workflow queue assignments are being cleared after rules run. The rule catches records that already have a queue assignment in the workflow and prevents later bin movement rules in the same exclusivity group from reapplying workflow, bin, or queue assignments.
This configuration is useful for workflows where reviewers or staff use manual queue assignment, including the Add to Queue option in Reader.

Creating the rule
Go to the workflow exclusivity group that controls bin movement.
Select New Rule.
Enter a descriptive name, such as Do Nothing If Queue Assignment Exists.
Use the same Configurable Joins base and rule type as the other rules in the exclusivity group.
Leave the rule trigger set to Upon Update (Deferred), unless your workflow design requires a different trigger.
Confirm that the correct exclusivity group is selected.
Set the rule as deterministic with an exclusive priority.
Enter a low, unique priority number so this rule runs before bin movement rules.
Select Save.

Adding a subquery filter for queue assignment existence
Select Subquey Filter.
Enter a clear name, such as Queue Assignment in App Review Workflow Exists.
Leave Type set to Dependent subquery.
Leave Aggregate set to Exists.

Joining to the workflow queue
In the subquery filter, select Join.
Under Application, select Workflow Bin User Queue.
Select Continue, then select Save.
This join limits the rule to records with an existing queue assignment.

From the same subquery filter, select Join again.
Under Workflow Bin User Queue, select Workflow.
Select Continue, then select Save.

Filter to the current workflow
In the subquery filter, select Filter.
Select Name.
Leave the operator set to IN.
Select the workflow that the exclusivity group supports.
Select Save.

Set the rule action
Select Save to finish the subquery filter.
In the rule action section, select No Action Rule.
Save the rule.
When ready, edit the rule and set Status to Active.
When a record meets this rule, later rules with higher priority numbers in the same exclusivity group are skipped. The record keeps its existing queue assignment.

⭐ Best practice
Create one do nothing rule for each workflow exclusivity group where existing manual queue assignments should be preserved.
