Dynamic creation of node in ABAP WD

Hi All,

Can anyone please suggest me why in ABAP webdynpro the second code is more prefareable then the first one.

It's mentioned in SAP material that the 2nd code is more prefarable.

1) lr_parent_node = wd_context->get_child_node(

name = '<parent_node>' )

lr_parent_node_info = lr_parent_node->get_node_info( )

2) lr_root_node_info = wd_context->get_node_info( )

lr_parent_node_info = lr_root_node_info->get_child_node(

name = '<parent_node>' )
