Hello Amit

I think very few people (me included) understand what you mean by <i>"...factory method to display ALV...".</i>

However, if you are using class CL_GUI_ALV_GRID then you have to call method GET_FRONTEND_FIELDCATALOG, modify the required columns ( e.g. ls_fcat-coltext), and afterwards call SET_FRONTEND_FIELDCATALOG.

If you are already using the new object model (CL_SALV_TABLE) then call method GET_COLUMNS and loop over the required column (CL_SALV_COLUMN) and modify them accordingly.

Hello Amit

Have a look at my sample report <b>ZUS_SDN_CL_SALV_TABLE_INTERACT</b> in thread

The method you are looking for is (CL_SALV_COLUMN) <b>SET_TECHNICAL</b>.

You need to do something like this for each field that you want to change. Get the COLUMN object and call the methods to set the labels at short medium and long.

  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( 'YOUR_FIELD_NAME' ).
      lr_column->set_short_text( 'Your Field').
      lr_column->set_medium_text( 'Your Field Name').
      lr_column->set_long_text( 'Your Long Field Name').
    catch cx_salv_not_found.                           
  endtry.
