background color in reports

Hello there,

In the code below:

 DATA: lv_key TYPE i.
 format color lv_key intensified no-gap on.

I keep getting the error

<b>

"COLOR LV_KEY" is not expected; only 1 to 7 or the relevant color IDs

</b>

May I know is there anyway I could get around that? Unfortunately I can not hard-code the color in this case.

Thanks a lot!

Regards,

Anyi
