Hi Mallika,

How can I set the cell color in ALV? http://www.sapfans.com/forums/viewtopic.php?t=52107

Thanks

Hi,

1.Add a color table of type LVC_T_SCOL to your output table, as shown in the example below:

2. Select your data and copy it into the output table.

3. Read one row of the output table at a time in the loop.

One row of the color table has three fields.

If field NOKEYCOL is set, you can change the color of key fields.

Assign values to the remaining fields as follows:

&#8722; If you want to color the entire row, assign the corresponding values to the fields of structure COLOR. Field fname does not receive a value in this case.

&#8722; If you want to color specific columns of the row only, you must append one row for each column to the color table. Assign the name of the desired column to field fname, and the corresponding values to the fields of structure COLOR.

eg:

DATA: BEGIN OF GT_OUTTAB OCCURS 0.

INCLUDE STRUCTURE <DDIC-Struktur>.

DATA: CT TYPE LVC_T_SCOL. "Table for colors

DATA: END OF GT_OUTTAB.

select * frm <tablename> into corresponding fields of table gt_outtab.

<b>If a whole row has to be coloured</b>

loop at gt_outtab into wa_outtab.

wa_outtab-CT-COLOR = <value of color>.

modify gt_outtab from wa_outtab index sy-tabix.

endloop.

<b>If you want to color specific columns of the row only</b>

loop at gt_outtab into wa_outtab where <field> = <fieldname>.

wa_outtab-CT-FNAME = <fieldname>.

wa_outtab-CT-COLOR = <value of color>.

modify gt_outtab from wa_outtab index sy-tabix.

endloop.

Hope u understood this.

Simy Abraham.

Hi

Coloring a row is a bit more complicated. To enable row coloring, you should add an additional field to your list data table. It should be of character type and length at least 4. This field will contain the color code for the row. So, let’s modify declaration of our list data table “gt_list”.

Adding the field that will contain row color data

As you guess, you should fill the color code to this field. Its format will be the same as explained before at section C.6.3. But how will ALV Grid know that you have loaded the color data for the row to this field. So, you make it know this by

*--- Internal table holding list data

DATA BEGIN OF gt_list OCCURS 0 .

INCLUDE STRUCTURE SFLIGHT .

DATA rowcolor(4) TYPE c .

DATA END OF gt_list . passing the name of the field containing color codes to the field “INFO_FNAME” of the layout structure.

e.g.

ps_layout-info_fname = <field_name_containing_color_codes>. “e.g. ‘ROWCOLOR’

You can fill that field anytime during execution. But, of course, due to the flow logic of screens, it will be reflected to your list display as soon as an ALV refresh occurs.

You can color an entire row as described in the next section. However, this method is less time consuming.

Coloring Individual Cells

This is the last point about coloring procedures for the ALV Grid. The procedure is similar to coloring an entire row. However, since an individual cell can be addressed with two parameters we will need something more. What is meant by “more” is a table type structure to be included into the structure of the list data table. It seems strange, because including it will make our list data structure deep. But anyhow ALV Grid control handles this.

The structure that should be included must be of type “LVC_T_SCOL”. If you want to color the entire row, this inner table should contain only one row with field “fname” is set to space, some color value at field “col”, “0” or “1” at fields “int” (intensified) and “inv” (inverse).

If you want to color individual cells, then for each cell column, append a line to this inner table which also contains the column name at field “fname”. It is obvious that you can color an entire column by filling this inner table with a row for that column for each row in the list data table. But, it is also obvious that, this will be more time consuming than the method at section C.6.1.

Again key field coloring will override your settings. That’s why, we have another field in this inner table called “nokeycol”. For each field represented in the inner table, set this field to ‘X’ to prevent overriding of key color settings.

In this procedure, again we must tell the control the name of the inner table containing color data. The field “CTAB_FNAME” of the layout structure is used for this purpose.

Adding inner table that will contain cell color data

A sample code to make the cell at row 5 and column ‘SEATSOCC’ colored

*--- Internal table holding list data

DATA BEGIN OF gt_list OCCURS 0 .

INCLUDE STRUCTURE SFLIGHT .

DATA rowcolor(4) TYPE c .

DATA cellcolors TYPE lvc_t_scol .

DATA END OF gt_list .

DATA ls_cellcolor TYPE lvc_s_scol .

...

READ TABLE gt_list INDEX 5 .

ls_cellcolor-fname = 'SEATSOCC' .

ls_cellcolor-color-col = '7' .

ls_cellcolor-color-int = '1' .

APPEND ls_cellcolor TO gt_list-cellcolors .

MODIFY gt_list INDEX 5 .

A juicy-brained guy may ask what happens if all these three procedures applied for coloring at the same time. And again the same answer is given as there is a priority among them. The priority order is: cell setting - row setting - column setting. Beside these, key field setting must be handled.
