SharePoint 2013 Workflow Status Codes
So this is a quick little post, but it can be a little hard to find sometimes. In your list with your workflows there is a set of status codes tied to their workflow. Honestly this is as much for me as it is for you. Here is the list of the status codes used to maintain the workflow statuses. Status - Value Not Started 0 Failed on Start 1 In Progress 2 Error Occurred 3 Canceled 4 Completed 5 Failed on Start ( retrying ) 6 Error Occurred ( retrying ) 7 Canceled 15 Approved 16 Rejected 17
