The code written

                AppModelDbInstanceEntity appModelDB = new AppModelDbInstanceEntity();
                appModelDB.AppId = 15;
                decimal appid = appModelDB.AppId;
                appModelDB.LogicalModelNm = "15";
                appModelDB.MachineId = GVMachineViewList.Rows[i].Cells[1].Text;
                appModelDB.InstanceNm = GVMachineViewList.Rows[i].Cells[2].Text; ;
                appModelDB.PhysDatabaseNm = GVMachineViewList.Rows[i].Cells[4].Text;
                appModelDB.ProductNm = GVMachineViewList.Rows[i].Cells[3].Text;

                mAdaptersecond.SaveEntity(appModelDB);

error comes when it tries to save.
