[HttpPost]
public ActionResult SpecificWorkflowReport(Report2ListViewModel wf)
{

      var getSpRecord = db.Mworkflow().ToList();

      var getRecord = (from u in getSpRecord
       select new Report2ListViewModel
          {
            WorkFlowType = u.WorkFlowType,
            WorkflowInstanceId = u.WorkflowInst,
            WorkFlowDescription = u.WorkFlowDesc,
          }).ToList();

          ViewBag.WorkflowType = wf.WorkFlowType;
          ViewBag.WorkflowInstanceId = wf.WorkflowInst;
          ViewBag.WorkFlowDescription = wf.WorkFlowDesc
