header in ALV using OOPS

Former Member · ‎2014 Jan 17

Hi all,

this is naresh.

i have displayed my table of data in ALV using set_table_for_first_display method.

but i could not add any header to that.

does reuse_commentary_write works in OOPs ALV?

in which parameter we need to pass it.

please share it.

thanks,

naresh.

Hi naresh,

You could not create header with the help of reuse_alv_commentary_write as because it is a function module . and you r doing the different approach by calling method.... Set_table_for_first_display

Alv header will be achieved by using splitter container please google it U will find ready code....

Hi Naresh,

   CALL METHOD cl_gui_alv_grid->set_table_for_first_display

Fill the field GRID_TITLE in the ALV Layout Structure - LVC_S_LAYO.
