How to avoid displaying zero in data cells in ALV

By /

Sometimes it’s useful to avoid displaying zero in ALV data cells, the easiest way is to use set_zero method of a column:

REPORT zkm_test.

TYPES:
  BEGIN OF ts_data,
    amount TYPE dmbtr,
    text   TYPE sgtxt,
  END OF ts_data,
  tt_data TYPE STANDARD TABLE OF ts_data.

DATA:
  lt_data    TYPE tt_data,
  ls_data    TYPE ts_data,
  lo_table   TYPE REF TO cl_salv_table,
  lo_columns TYPE REF TO cl_salv_columns,
  lo_column  TYPE REF TO cl_salv_column.

ls_data-amount = 1.   ls_data-text = 'first'.    APPEND ls_data TO lt_data.
ls_data-amount = 0.   ls_data-text = 'second'.   APPEND ls_data TO lt_data.
ls_data-amount = 2.   ls_data-text = 'third'.    APPEND ls_data TO lt_data.

CALL METHOD cl_salv_table=>factory
  IMPORTING
    r_salv_table = lo_table
  CHANGING
    t_table      = lt_data.

lo_columns = lo_table->get_columns( ).
lo_column = lo_columns->get_column( 'AMOUNT' ).
lo_column->set_zero( abap_false ).

lo_table->display( ).
