How can we use the saved alv grid layout in a report?

Question

I have a requirement where I go to se16n transaction and select a few fields of a table and extract the data of the table. Again I re-arrange the columns in the report and save it as a variant along with this new layout. Now how to call this variant in a report wherein I want only the re arranged positions of the column(fields) of the field catalog? Is there any function module available?

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.
