Error while opening the EXCEL Sheet from a Report Program

Question

Hi All,
I am getting an error saying 'SYLK: File Format is not valid' when my program is trying to open an excel sheet. I am using the function module WS_EXCEL to download it to excel sheet.
Following is the code:
Excel download
types: begin of t_excel,
         c01(20),
         c02(20),
         c03(20),
         c04(20),
         c05(70),
         c06(20),
         c07(20),
         c08(20),
         c09(20),
         c10(20),
       end of t_excel.
data: a00_excel type standard table of t_excel.
concatenate 'C:\' sy-repid sy-uzeit 'FILE01' '.xls' into z_fname.
condense z_fname no-gaps.
call function 'WS_EXCEL'
      exporting
           filename = z_fname
      tables
           data     = a00_excel
      exceptions
           others   = 1.
if sy-subrc ne 0.
   message e019(zsd).
  Download to Excel failed.
endif.
a00_excel contains the data that is to be downloaded into the excel sheet. I used the same code in the other program it is working fine. If you see in the type declaration for C5 its 70 characters, i tried putting it as same as others to 20... still it doesnt work.
Thank You,
Suresh

Not sure man,  your code works ok for me.
report zrich_0001.
types: begin of t_excel,
c01(20),
c02(20),
c03(20),
c04(20),
c05(70),
c06(20),
c07(20),
c08(20),
c09(20),
c10(20),
end of t_excel.
data: a00_excel type standard table of t_excel.
data: x00_excel like line of a00_excel.
data: z_fname type string.
x00_excel-c01 = 'A'.
x00_excel-c02 = 'B'.
x00_excel-c03 = 'C'.
x00_excel-c04 = 'D'.
x00_excel-c05 = 'E'.
x00_excel-c06 = 'F'.
x00_excel-c07 = 'G'.
x00_excel-c08 = 'H'.
x00_excel-c09 = 'I'.
x00_excel-c10 = 'J'.
append x00_excel to a00_excel.
x00_excel-c01 = 'K'.
x00_excel-c02 = 'L'.
x00_excel-c03 = 'M'.
x00_excel-c04 = 'N'.
x00_excel-c05 = 'O'.
x00_excel-c06 = 'P'.
x00_excel-c07 = 'Q'.
x00_excel-c08 = 'R'.
x00_excel-c09 = 'S'.
x00_excel-c10 = 'T'.
append x00_excel to a00_excel.
concatenate 'C:' sy-repid sy-uzeit 'FILE01' '.xls' into z_fname.
condense z_fname no-gaps.
call function 'WS_EXCEL'
     exporting
          filename = z_fname
     tables
          data     = a00_excel
     exceptions
          others   = 1.
if sy-subrc ne 0.
  message e019(zsd).
*  download to excel failed.
endif.
