I have a quite specific requirement from company management to set 'antedates' ("Started" and "Last run" dates) for some documents on the workflow status page of OOTB Approval Workflow (see picture).
E.g. shift these dates 3 months back. Are there any methods to do this, except on DB level?
SPWorkflow class, unfortunately, doesn't have any Update methods, so I can't use this class to change Created and Modified properties. Maybe someone knows an internal method which I can use for it? By the way, how does SharePoint set these dates under the hood?
