## Short answer

Resolve SyteLine workflows stuck in pending or in-progress status. Covers ION Workflow configuration, approval routing errors, and workflow engine troubleshooting.

## Content

**Intro:** A SyteLine workflow that sits in 'Pending' or 'In Progress' status indefinitely blocks business transactions that require approval, such as purchase requisitions, engineering change orders, and customer credit holds. The error 'Workflow engine unable to advance task: no valid approver found' or simply a workflow that never moves past the first approval step indicates a configuration problem in the ION Workflow setup, a missing approver assignment, or the workflow engine service itself being stopped.

**Sections:**

#### Diagnosing Stuck Workflow Issues

**Body:** SyteLine workflows managed through Infor ION Workflow or the built-in SyteLine workflow engine can stall at any approval step. The ION Workflow monitor shows the current state of each workflow instance and identifies which step is blocked. For the native SyteLine workflow engine, the Workflow History form and the SLWorkflow event log provide the diagnostic information needed to pinpoint the failure.

**Bullets:**

- Open the ION Workflow Monitor in Infor OS Portal to view all active workflow instances and identify which step is in 'Pending' or 'Error' state
- Check the SyteLine Workflow History form: filter by Status = 'In Progress' and review the 'Current Step' and 'Assigned To' fields for the blocked step
- Look for 'Workflow engine unable to advance task: no valid approver found for step [StepName]' in the SyteLine event log, indicating a missing approver assignment
- Verify the ION Workflow Connection Point is active and connected by checking the ION connection status in Infor OS Portal > ION > Connection Points
- Test if the workflow engine service is running: check Windows Services for 'Infor ION Workflow Engine' or the SyteLine-native 'SLWorkflowService' and verify status is Running

#### Resolving Stuck Workflows

**Body:** The resolution depends on why the workflow stalled. If the approver is missing or unavailable, reassign the workflow task to an alternate approver or add the missing user to the approval role. If the workflow engine service is stopped, restart it and the queued workflows will resume processing. If the workflow definition itself is misconfigured, correct the routing rules and re-activate the workflow.

**Bullets:**

Reassign a stuck workflow task: ION Workflow Monitor > select the stuck task > Actions > Reassign > select an alternate approver from the available users list

Add missing approvers to the workflow role: ION Workflow > Administration > Roles > select the approval role > add the required users who were omitted

Restart the workflow engine: net stop InforIONWorkflowEngine && net start InforIONWorkflowEngine (or restart SLWorkflowService for native SyteLine workflows)

For workflows stuck due to a configuration error, cancel the stuck instance from the Workflow Monitor, correct the workflow definition, re-activate it, and resubmit the transaction

Clear the ION message queue if workflow messages are backed up: ION > Monitors > Data Flow > check for messages in 'Error' or 'Pending' status and reprocess or purge

#### Workflow Reliability Configuration

**Body:** Preventing stuck workflows requires proper approver backup assignments, workflow timeout configuration, and proactive monitoring of workflow queue health. Every approval step should have a designated backup approver and a timeout escalation rule so that no workflow can remain in pending status beyond a defined business SLA.

**Bullets:**

Configure backup approvers for every workflow step: ION Workflow Designer > each approval step > set 'Backup Approver' to a manager or role that can act when the primary approver is unavailable

Set workflow timeout escalation: define a maximum pending time (e.g., 48 hours) after which the workflow automatically escalates to the next level of management

Enable email notifications for workflow assignments so approvers are immediately aware of pending tasks and act within the expected SLA

Schedule a daily workflow health check report that lists all workflows pending longer than 24 hours, sent to the workflow administrator for manual intervention if needed

**Cta:** Netray AI agents monitor SyteLine workflow queues in real time, detect stuck approvals within minutes, auto-escalate to backup approvers, and ensure no business transaction is delayed. Get started.
