See this and do accordingly

1. add one more field to ur final internal table say COLOR(4)

2. in layout wa_layout-style_fname = 'COLOR'. " if its grid

wa_layout-style_fieldname = 'COLOR'. "if its list

3. read table itab index 3.

itab-color = 'C410'.

modify itab index 3

4. see program SHOWCOLO for all color codes

1. Add a field of data type CHAR(3) to the internal output table.

2. Enter the color code in the appropriate field of the row to be colored in the internal

output table:

Code: 'Cxy'

C = Color (all codes begin with 'C')

x = color number ('1' - '9')

y = highlight ('0' = off, '1' = on)

3. Assign the internal output table color code field name to the IS_LAYOUT importing

structure IS_LAYOUT-INFO_FIELDNAME field and pass this structure in the ALV call

interface.

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”.

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 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.

See the sample code for coloring

There are a number of ways to create a fieldcat.
For the purpose of this example i will build the fieldcatalog manualy
by populating the internal table fields individually and then
appending the rows. This method can be the most time consuming but can
also allow you more control of the final product.

Beware though, you need to ensure that all fields required are
populated. When using some of functionality available via ALV, such as
total. You may need to provide more information than if you were
simply displaying the result
I.e. Field type may be required in-order for
the 'TOTAL' function to work.
