Pre-requisites:
Required role privilege 'Manage Workflow Rules' on the project where a failed workflow instance is to be resumed.
Follow the steps for checking progress on a workflow instance then go to the particular workflow instance on which you need to resume workflow. You can only resume workflow if the current workflow status shows as 'Failed'.
Click the workflow status 'FAILED' to view the progress level of the workflow instance. The 'Workflow Status' screen will appear.
To resume a failed workflow, you need to ensure that the required condition to resume the workflow is satisfied. E.g. if the workflow for a file had failed earlier as the concerned user was unable to access the project folder, that user should get the required access to the concerned project folder for the workflow to be able to resume.
Click the 'Resume Workflow' button at the top right will resume the failed workflow only if the required condition to resume workflow is satisfied.
By performing the above steps only the selected workflow will resume for the selected object i.e. file, form, or custom object. If there are other workflows applied to the same object, they will remain unaffected.
