IBase Hierarchy Issue - Not able to collapse child nodes

Hi All,

We had a customization in  Component: IBHIER View: IBHIER/TreeEnhanced  Method: IF_BSP_WD_TREE_NODE~GET_CHILDREN to always expand few IBase tree child nodes based on some conditions. But now the requirement is to expand the node only first time(loading the page). Is this possible to achieve it without using a local variable(flag kind of) to mark the first time page load.

I tried using the method is_expanded(). lr_child->if_bsp_wd_tree_node~is_expanded( ) = abap_false but I did not get the expected result.

Thanks in advance.

Regards,

Nalini
