Code snippet to set the Column Description as the Column Name when the Column description is empty in the ALV generated by SALV model.
Sometimes you want to do some quick programming. When you use the generic types to define the Itab, SALV doesn’t show any description.
Column Description as Column Name
* DATA: lo_cols TYPE REF TO cl_salv_columns,
lo_column TYPE REF TO cl_salv_column_list,
lt_cols TYPE salv_t_column_ref,
ls_cols LIKE LINE OF lt_cols.
DATA: lv_short TYPE scrtext_s.
DATA: lv_med TYPE scrtext_m.
DATA: lv_long TYPE scrtext_l.
* Columns lo_cols = o_salv->get_columns( ). lo_cols->set_optimize( 'X' ).
* For each column
* If Short description is not there, set Short
* If Medium description is not there, set Medium
* If Long description is not there, set Long
lt_cols = lo_cols->get( ).
LOOP AT lt_cols INTO ls_cols.
lo_column ?= ls_cols-r_column. "Narrow casting
IF lo_column->get_short_text( ) IS INITIAL.
lv_short = ls_cols-columnname.
lo_column->set_short_text( lv_short ).
ENDIF.
IF lo_column->get_medium_text( ) IS INITIAL.
lv_med = ls_cols-columnname.
lo_column->set_medium_text( lv_med ).
ENDIF.
IF lo_column->get_long_text( ) IS INITIAL.
lv_long = ls_cols-columnname.
lo_column->set_long_text( lv_long ).
ENDIF.
ENDLOOP.
