Error in copy of BCALV_TREE_SIMPLE_DEMO

Question

I copied BCALV_TREE_SIMPLE_DEMO  to a z version,
changed it with own structure
DATA: gt_sflight      TYPE zhpa_vakantie_struc OCCURS 0, "sflight OCCURS 0,      "Output-Table
now when running an error occurs, i think this has to do with the screen collumn layout???????
When in debug mode i see somewhere that the code is looking for fields from structure sflight!
Anyone a clue??

Answer 1

Maybe the problem comes from gt_sort then :
form build_sort_table.
  data ls_sort_wa type lvc_s_sort.
* create sort-table
  ls_sort_wa-spos = 1.
  ls_sort_wa-fieldname = 'CARRID'.
  ls_sort_wa-up = 'X'.
  ls_sort_wa-subtot = 'X'.
  append ls_sort_wa to gt_sort.
  ls_sort_wa-spos = 2.
  ls_sort_wa-fieldname = 'CONNID'.
  ls_sort_wa-up = 'X'.
  ls_sort_wa-subtot = 'X'.
  append ls_sort_wa to gt_sort.
  ls_sort_wa-spos = 3.
  ls_sort_wa-fieldname = 'FLDATE'.
  ls_sort_wa-up = 'X'.
  append ls_sort_wa to gt_sort.
endform.                               " BUILD_SORT_TABLE
However, you get this error because there are differences between the structure of the table containing your data and the ones defining your field catalog or the sorting order.
