Where can we catch the event which leads to downloading a report to a local

Question

Hi frnds,
can u help me out . actaully ,i  have a classical interactive report. it has many headings.Because of the initial headings ,if i try to download that report to a local file ,the column allignments are disturbed.
So,one way i feel to get the download correctly ,is that ,some how i can catch the event whcih leads to the download of the report ,and based on the occurence of that event ,i can restrict the page headings to appear in the downloaded spreadsheet ,so that the there are no, unwanted columns getting inserted in between .

hi,
you can have selection screen field : "parameters : p_disvar like disvariant-variant."  and at event selection scree you can call the below function and select the variant create for the report.
"at selection-screen on value-request for p_disvar.
  call function 'REUSE_ALV_VARIANT_F4'
       exporting
            is_variant          = g_variant
          I_TABNAME_HEADER    =
          I_TABNAME_ITEM      =
          IT_DEFAULT_FIELDCAT =
            i_save              = g_variant_save
       importing
            e_exit              = h_exit
            es_variant          = gx_variant
        exceptions
            not_found           = 1
            program_error       = 2
            others              = 3.
  if sy-subrc is initial and h_exit is initial.
    g_variant-variant = gx_variant-variant.
    p_disvar          = gx_variant-variant.
  else.
    message id sy-msgid type 'S'
                 number sy-msgno
                 with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  endif.
