First off, OpsAnalitica is not allowed to delete any completed checklists out of the platform for clients.
If you don't have the proper roles to delete a checklist yourself then you need to contact your OpsAnalitica Administrator for your company and they can help you with this.
Here is how you can determine if you have the proper roles and delete a checklist.
You will know if you have the proper roles to delete a checklist if you see the Delete Button in the Top Right Corner of the Inspection Report.
If you don't have that button, you are unable to delete the Inspection Report.
You will need to contact your company's OpsAnalitica Admin to delete the checklist for you.
