      EX_ICLIENT_WRK.HTMLAREA.Visible = False) And

      (EX_SHEET_HDR.SHEET_STATUS = "SUB" Or

         EX_SHEET_HDR.SHEET_STATUS = "SFA") Then

   EX_ICLIENT_WRK.REFRESH_APPRVL.Visible = True;

   If &mode = "Inquiry" And

         EX_SHEET_HDR.SHEET_STATUS.Value = "SUB" And

         &access = "A" Then

      If &cbWithdrawal Then

         EX_ICLIENT_WRK.REFRESH_APPRVL.Visible = True;
