There is No data for me in Orphan graph. Can you suggest anything here ?

Very helpful, completed and task validation successful!

Thank you

A simpler workflow version would be just to use the Set Values activity with the following string substitution

Short Description = Workflow launched for task number ${current.number} 

Thanks Omarali, since this is a workflow with some script logic, there are multiple ways to achieve the same result. For our purposes, we try to display using scratchpad and a run script, only for scalability by setting all variables in the first activity. In large workflows, having all the variables captured in one activity can help for maintenance or update purposes. But what you show is perfectly acceptable. Thanks. 

Here is what I tried

Created a workflow

- Name: Remediate Orphan WF
- Table: Orphan CI Remediation [orphan_ci_remediation]

Added 2 Core actions:

- Run Script
- Set Values

Connect the actions

1. Begin
2. Run Script
3. Set Values
4. End

Action: Run Script

workflow.scratchpad.currentnumber = current.number;

Action: Set Values

Short description 

Workflow launched for task number ${workflow.scratchpad.currentnumber}

Finish your workflow

Do not forget to Publish your workflow!

After the workflow is finished Create a CMDB Remediation Rule.

Create a CMDB Remediation Rule

- Name: Remediate Orphans
- Task type: Orphan CI Remediation
- Execution: Manual
- Workflow: [Your workflow name] "Remediate Orphan WF"

Set Health Preferences

 In the category "Health Metrics" select "Orphan" Metric and activate "Create Task"
