Pre-requisites:
You must have the 'Manage Workflow Rules' role privilege on the project where a workflow instance is to be cancelled.
To begin, kindly click here to learn how to check the progress on a workflow instance and follow the steps mentioned.
Right-click the node where the workflow is currently moving and select the 'Cancel Workflow' option to cancel this workflow instance. The right-click option to cancel workflow won't appear for actions not yet executed as part of the selected workflow instance.
Note: Canceling a workflow won't automatically clear tasks that would have already been assigned as part of the workflow and are pending completion. Such tasks need to be cleared manually using the 'Clear Tasks' option for files / 'Clear Tasks' option for forms as applicable.
By performing the above steps, only the selected workflow will cancel for the selected object, i.e. file, form or custom object. If other workflows are applied to the same object, they remain unaffected.
In case the workflow on the selected file, form, or custom object is in 'Failed' status, it cannot be cancelled directly. It has to be first resumed, and only then can the workflow on the selected object be cancelled. Click here to learn how to resume a failed workflow.
