hi all alv 2 texts headers

hi

i have developed alv and in that i am displaying field names at the top and field values at the bottom.

my question is: i want to display 2 text headers at the top i.e. above field names.

-

mat info | mat value

-

matno | plant | mattype | storageloc | value | quantity

-

here values are displayed.

-

in the above alv output matinfo and mat value are just text (header text) which are above field names.

how can i bring these 2 text above fields names in alv..

thanx

rocky
