How to Display Headers for ALV report using classes?

[Former Member]

Can ayone tell me how to create headers as we do using COMMENTARY_WRITE, but by using classes.? is there any other way of doing it?

If you illustrate with an example, that would be great.

Thnx in advance

hi,

I am not sure this answers your question but when creation a ALV tree using classes you can build the heading in the same way as the COMMENTARY_WRITE and then include the resultant table (it_list_commentary) when setting the ALV tree for first display:

CALL METHOD tree1->set_table_for_first_display

EXPORTING

is_hierarchy_header = l_hierarchy_header

it_list_commentary = lt_list_commentary

i_logo = l_logo

• i_background_id = 'ALV_BACKGROUND'

i_save = 'A'

is_variant = ls_variant

CHANGING

it_outtab = it_setupalv

• gt_sflight "table must be emty !!

it_fieldcatalog = gt_fieldcatalog.
