Hi

I want to build a tree into a ALVGRID. I want to have the header data ( Ekko) on the main row and the details (EKPO) hidden in the tree.

How does one progam a row to hide a a sub row?

Hi

I did make a copy of BCALV_TREE_SIMPLE_DEMO deleted the flight tables and moved my own data(ekko) into the tables.

Obviously i don't understand the logic behind this program.

I get the following error.

Runtime errors ETWA_NOT_ASSIGNED

I've noticed that if i only use one field the report display without errors but i now don't get the line items under one tree.


form build_sort_table.

  data ls_sort_wa type lvc_s_sort.

* create sort-table
  ls_sort_wa-spos = 1.
  ls_sort_wa-fieldname = 'EBELN'.
  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 = 'EKGRP'.
*  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 = 'EKORG'.
*  ls_sort_wa-up = 'X'.
*  append ls_sort_wa to gt_sort.

endform.                               " BUILD_SORT_TABLE
