Fill with color all columns maximums in ALV table

Question

I need to put color into all the cells with values inside each column.

I want to show something like this.

Here is my code:

    SORT gt_sehir_dilim_alv BY
          saat1 DESCENDING
          saat2 DESCENDING
          saat3 DESCENDING
          saat4 DESCENDING
          saat5 DESCENDING
          saat6 DESCENDING
          saat7 DESCENDING.

  LOOP AT gt_sehir_dilim_alv INTO gs_sehir_dilim_alv.
    lv_index = sy-tabix.

    IF lv_index EQ '1'.

      wa_cellcolor-fname = 'SAAT1'.
      wa_cellcolor-color-col =  1.
      wa_cellcolor-color-int = '1'.
      wa_cellcolor-color-inv = '0'.
      APPEND wa_cellcolor TO gs_sehir_dilim_alv-cellcolor.
      CLEAR: wa_cellcolor.
      MODIFY gt_sehir_dilim_alv FROM gs_sehir_dilim_alv
      TRANSPORTING cellcolor.


      wa_cellcolor-fname = 'SAAT2'.
      wa_cellcolor-color-col =  1.
      wa_cellcolor-color-int = '1'.
      wa_cellcolor-color-inv = '0'.
      APPEND wa_cellcolor TO gs_sehir_dilim_alv-cellcolor.
      CLEAR: wa_cellcolor.
      MODIFY gt_sehir_dilim_alv FROM gs_sehir_dilim_alv

      APPEND wa_cellcolor TO gs_sehir_dilim_alv-cellcolor.
      CLEAR: wa_cellcolor.
      MODIFY gt_sehir_dilim_alv FROM gs_sehir_dilim_alv

      wa_cellcolor-color-col =  1.
      wa_cellcolor-color-int = '1'.
      wa_cellcolor-color-inv = '0'.
      APPEND wa_cellcolor TO gs_sehir_dilim_alv-cellcolor.
      CLEAR: wa_cellcolor.
      MODIFY gt_sehir_dilim_alv FROM gs_sehir_dilim_alv

Answer 1

Here is the sample how to do it for 3 fields of table ANLC without additional itabs and loops:

TYPES: BEGIN OF t_assets,
             idx   TYPE char6,
             bukrs TYPE anlc-bukrs,
             anln1 TYPE anlc-anln1,
             nafap TYPE anlc-nafap,
             nafag TYPE anlc-nafag,
             answl TYPE anlc-answl,
           t_color TYPE lvc_t_scol,
          END OF t_assets.

DATA: gt_assets TYPE TABLE OF t_assets.

SELECT DISTINCT bukrs, anln1, abs( nafap ) AS nafap, abs( nafag ) as nafag, answl
  INTO CORRESPONDING FIELDS OF TABLE @gt_assets
  FROM anlc
 WHERE nafap <> 0 OR nafag <> 0 OR answl <> 0.

LOOP AT gt_assets ASSIGNING FIELD-SYMBOL(<fs_asset>).
  <fs_asset>-idx = sy-tabix.
  CONDENSE <fs_asset>-idx.
ENDLOOP.

DATA(maximums) = REDUCE t_assets( INIT max = VALUE t_assets( )
                 FOR <m> IN gt_assets NEXT 
                                      max-nafap = COND #( WHEN <m>-nafap > max-nafap THEN <m>-nafap ELSE max-nafap )
                                      max-nafag = COND #( WHEN <m>-nafag > max-nafag THEN <m>-nafag ELSE max-nafag )
                                      max-answl = COND #( WHEN <m>-answl > max-answl THEN <m>-answl ELSE max-answl )
                                      max-idx = condense( val = gt_assets[ nafap = max-nafap ]-idx ) && condense( val = gt_assets[ nafag = max-nafag ]-idx ) && condense( val = gt_assets[ answl = max-answl ]-idx ) ).

gt_assets[ idx = maximums-idx(2) ]-t_color   = VALUE lvc_t_scol( BASE gt_assets[ idx = maximums-idx(2) ]-t_color ( fname  = 'NAFAP' color-col = col_negative ) ).
gt_assets[ idx = maximums-idx+2(2) ]-t_color = VALUE lvc_t_scol( BASE gt_assets[ idx = maximums-idx+2(2) ]-t_color ( fname  = 'NAFAG' color-col = col_negative ) ).
gt_assets[ idx = maximums-idx+4(2) ]-t_color = VALUE lvc_t_scol( BASE gt_assets[ idx = maximums-idx+4(2) ]-t_color ( fname  = 'ANSWL' color-col = col_negative ) ).

TRY.
    cl_salv_table=>factory( IMPORTING r_salv_table = DATA(alv) CHANGING t_table = gt_assets ).
  CATCH cx_salv_msg INTO DATA(message).
ENDTRY.

TRY.
    DATA(columns) = alv->get_columns( ).
    columns->set_color_column( 'T_COLOR' ).
  CATCH cx_salv_data_error.                         "#EC NO_HANDLER
ENDTRY.

alv->display( ).

The code is rather self-commenting but I'd put some comments:

1. First and foremost you need index for each line to be able to pick them
2. Then while finding maximums with REDUCE I made a trick of putting all the MAX indices into single field, which should be lengthy enough to hold them (current snippet is for 2char index i.e. for tables up to 99 rows). This is dirty but anyway it's better than additional loop
3. Finally I fill colors by table expressions by picking index for the correspondent field

With a little bit of effort this piece can be adapted to any number of fields or to dynamic style without field names whatsoever.

Answer 2

I created another extra itab i put all the values into it. After by SORT DESCENDING order i pick index 1 compare with table itab now im able to give cell colors to highest values.
