Pre-requisites:
Required role privilege 'Manage Workflow Rules' on the project where a workflow instance is to be transitioned.
Follow the steps for checking progress on a workflow instance then go to the particular workflow instance on which you need to transition workflow.
Right-click the node where the workflow is currently moving and select the 'Transition Workflow' option to transition this workflow instance.
Note: Transitioning a workflow won't automatically clear tasks that would have already been assigned as part of the workflow and are pending to complete. Such tasks can be cleared manually using the 'Clear Tasks' option for files / the 'Clear Tasks' option for forms as applicable.
Selecting the 'Transition Workflow' option here will ensure the workflow moves to the next node. The right-click option to transition workflow won't appear for any actions not yet executed as part of the selected workflow instance.
By performing the above steps, only the selected workflow will transition 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.
In case the workflow on the selected file, form, or custom object is in 'Failed' status, it cannot be transitioned directly. It has to be first resumed and only then the workflow on the selected object can be transitioned. Click here to learn how to resume a failed workflow.
