Hi,
i use ALV-Tree and try to expand the first hierarchie.
I try this:
TRY.
GR_TREE_NODE = GR_TREE_NODES->ADD_NODE(
RELATED_NODE = ROOT_KEY
*EXPANDER = ABAP_TRUE*
RELATIONSHIP = CL_GUI_COLUMN_TREE=>RELAT_FIRST_CHILD
TEXT = 'Meldungen').
CATCH CX_SALV_MSG.
ENDTRY.
but this element will not be expandet?
I know this for expand all: CALL METHOD GR_TREE_NODES->EXPAND_ALL.
but want to expand only the first hierarch-elemet (root).
Can anyone tell me what i'm doing wrong?
Thanks.
Regards, Dieter
