Hi.

Let me see the source code.

CL_SALV_TABLE or CL_GUI_ALV_GRID

DATA: lt_fcat type lvc_t_fcat,

lv_fname type fieldname value '<Your FName>'.

FIELD-SYMBOLS: <fcat> type lvc_s_fcat.

CALL METHOD alv_grid->get_frontend_fieldcatalog

IMPORTING

et_fieldcatalog = lt_fcat.

read table lt_fcat assigning <fcat> with key fieldname = lv_fname.

if sy-subrc is initial.

<fcat>-COLTEXT = <fcat>-SCRTEXT_L = <fcat>-SCRTEXT_M = <fcat>-SCRTEXT_S = <fcat>-SELTEXT = '<Your new Description>'.

endif.

CALL METHOD alv_grid->set_frontend_fieldcatalog

Please refer to the program "SALV_DEMO_TABLE_COLUMNS" which is an example of how to access the columns.

the important part is:

data: gr_table   type ref to cl_salv_table.

data: lr_columns type ref to cl_salv_columns_table,
        lr_column  type ref to cl_salv_column_table.

  lr_columns = gr_table->get_columns( ).

  try.
      lr_column ?= lr_columns->get_column( 'COLUM_TECNICAL_NAME' ).
      lr_column->set_short_text( 'S TEXT' ).
      lr_column->set_medium_text( 'MEDIUM TEXT' ).
      lr_column->set_long_text( 'LONG DESCRIPTION' ).
    catch cx_salv_not_found.           
  endtry.
