Change color in alv column

Question

how do change color of a column in ALV.

Answer 1

Hi
The below abap program shows how to change the colour of individual ALV cells /fields. Only a small number of changes are required from a basic ALV grid which include adding a new field to ALV data declaration table(it_ekko), populating this field with the field name identifier and colour attributes and finally adding an entry to layout control work area. These changes are highlighted in bold below.

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.
