ALV REPORT : Can i fill my own string in one of the columns

Hello Friends

I have created an ALV report with 3 columns and the data is getting from a ztable. Now I want to create 4th column and want the string 'abcd' to be displayed in all the cells of this particular column. I don't have this field in the ztable. I just want to display this on ALV report as shown below.

NAME AGE SALARY COLUMN-4

Mike 40 40/hour abcd

Ben 30 39/hour abcd

Cathy 12 50/hour abcd

Can I do this? Any feedback will be greatly appreciated.

Thanks

Ram
