if this is not a typo, change the case & check

EXPORTING I_STRUCTURE_NAME = 'kna1'

EXPORTING I_STRUCTURE_NAME = 'KNA1'

Hi,

There is no need to KNA1 structure to pass set_table_for_first_display ih you have field catalog


    call method grid1->set_table_for_first_display
      changing
        it_outtab                     = t_kna1[]
        it_fieldcatalog               = t_fcat1[]
      exceptions
        invalid_parameter_combination = 1
        program_error                 = 2
        too_many_lines                = 3
        others                        = 4.

I want to know how to increase the size of the table in the output.

Ben, you can simply make the container bigger. Go to screen painter and increase the size of the container, you may need to increase the default size of the screen as well.
