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.
