Tree, I need some help

Hi guys,

I'm developing a tree application by wd abap, it will be like MMBE.

I need to display all fields of structure in a node or item.

Example:

Structure :

BUKRS

WERKS

LGORT

MATNR

Layout:

BUKRS A

|_ WERKS LGORT MATNR

|_ WERKS LGORT MATNR

BUKRS B

|_WERKS LGORT MATNR

I created nodes "NODE1" and "ITEM1" type strucure and add all field, assigned to tree container, created methods to fill both, but when I test, only appear a tree without any description. How could I fill nodes to appear entire row?
