FORM init_tree.

DATA : gt_fieldcatalog type lvc_t_fcat.

sort gt_fieldcatalog by scrtext_l.

change fieldcatalog

DATA : ls_fieldcatalog type lvc_s_fcat.

loop at gt_fieldcatalog into ls_fieldcatalog.

case ls_fieldcatalog-fieldname.

endcase.

modify gt_fieldcatalog from ls_fieldcatalog.

endloop.

append ls_sort_wa to gt_sort.

append ls_sort_wa to gt_sort.

create container for alv-tree

ENDFORM. "plus

Well, my problem is that program returns me an error (GETWA_NOT_ASSIGNED) when i add :

ls_sort_wa-spos = 2.
ls_sort_wa-fieldname = 'KOSTL'.
ls_sort_wa-up = 'X'.
ls_sort_wa-subtot = 'X'.
append ls_sort_wa to gt_sort.

In fact i'd like such an alv :

kostlg/kostl |--

Data--

kostlg1

kostl1

kostl2

kostlg2

etc etc...

I've been through many examples but didn't find why an error occurs.

Please help me guys,

Thank you.
