Running into a frustrating issue with shift assignments in AM 2021.2. When supervisors assign operators to shifts through the workflow, the assignments are processed and show as completed in the workflow monitor, but the actual operator roster in Resource Management doesn’t update. This creates a disconnect where the workflow thinks operators are assigned, but the shop floor schedule shows no one assigned to those stations.
I’ve used the Workflow Debugger to trace the execution, and the shift assignment mapping appears to complete without errors. The Operator ID validation passes successfully for all affected assignments. However, the final step where the roster should update just doesn’t fire. This is causing resource shortages on the floor because our dispatching system relies on the roster data. Anyone dealt with roster sync issues between workflow and resource management?
This sounds like a transaction boundary issue. In AM 2021.2, the shift assignment workflow uses distributed transactions across workflow and resource management schemas. If the transaction coordinator isn’t properly configured, the workflow transaction can commit while the resource management transaction rolls back silently. Check your transaction manager logs for any XA transaction warnings or rollback messages. Look specifically for ‘Resource Manager Rollback’ entries that coincide with your shift assignment timestamps.
Beyond the calendar issue, you should also verify the workflow’s resource management service connection. In 2021.2, there’s a known issue where the workflow engine caches stale resource service endpoints after system updates. This can cause the roster updates to be sent to an inactive service instance. Check ServiceRegistry.xml and confirm the ResourceManagementService endpoint is pointing to your active instance.
You need to address three interconnected issues to fix the roster sync problem:
Shift Assignment Mapping: The workflow is correctly mapping operator IDs to shift assignments, but it’s not validating the target shift period existence before attempting the roster insert. You need to add a pre-validation step in your workflow configuration. Open Workflow Debugger > ShiftAssignmentWorkflow and add a validation activity before the roster update:
- Insert new activity: ‘ValidateShiftPeriodExists’
- Configure it to query ResourceCalendar table for the target shift date/time
- Set failure action to ‘Rollback and Notify’
This prevents the foreign key violations you’re seeing in the transaction logs.
Operator ID Validation: While your operator IDs are validating successfully, the validation is happening too early in the workflow. The operator status can change between validation and roster update, especially in high-turnover environments. Move the operator validation step to immediately precede the roster update activity. In the workflow configuration, reorder the activities so ‘ValidateOperatorStatus’ executes right before ‘UpdateOperatorRoster’. This reduces the window for operator status changes.
Workflow Debug Tracing: Enable detailed transaction tracing to catch future sync failures early. In Workflow Debugger settings, enable these trace flags:
workflow.trace.transaction.enabled=true
workflow.trace.resource.updates=true
workflow.trace.rollback.reasons=true
Also critical - verify your resource management service endpoint is current. Check ServiceRegistry.xml and ensure ResourceManagementService points to your active instance. If you’ve done any server migrations or load balancer changes recently, the workflow might be calling a stale endpoint.
Finally, add compensating logic to handle partial failures. If the roster update fails but the workflow assignment succeeds, you need an automatic retry mechanism. Configure the workflow to catch RosterUpdateException and queue the assignment for retry after a 5-minute delay. This prevents the disconnect between workflow status and actual roster state.
Implement these changes and test with a small batch of shift assignments first. Monitor the transaction logs to confirm both workflow and resource management transactions are committing successfully.
First thing to check - are you seeing any orphaned transactions in the resource management tables? Sometimes the workflow completes but leaves uncommitted data. Query the OperatorAssignment table directly and see if the records exist there but just aren’t visible in the UI.
The foreign key violation makes sense. We had a similar problem last year. Make sure your resource calendar has shift periods defined for all the dates you’re trying to assign. The workflow validates operator IDs but doesn’t check if the target shift period exists in the calendar before attempting the roster insert.
