alv tree

Former Member — Sun, 10 Jun 2007 10:43:52 GMT

hello!

I created a report similar to transaction IH03 in its results ( not in the code ).

Instead of parameter equipment in the selection screen i have select options.

My problem is that when i have more then one equipment, the tree is not correct due to wrong tree nodes.

I need to create a situation that when i have new equipment the nodes will be refreshed if i understand the tree behavior.

I used class CL_GUI_ALV_TREE and method TREE1=>ADD_NODE.

Can anyone tell me how to refresh the nodes or an example for that.

thanks

Yifat

Hello Yifat

Class <b>CL_GUI_ALV_TREE</b> has two methods for refreshing the display:

- FRONTEND_UPDATE (Sends Changed/Inserted Nodes to Control)
- UPDATE_CALCULATIONS (Recalculate Columns)

The second methods implicitly calls method FRONTEND_UPDATE except if you suppress it using parameter NO_FRONTEND_UPDATE = 'X'.

Regards

CALL METHOD ALV_TREE->FRONTEND_UPDATE.

hi!

thanks for your answer.

My program work as a loop , and suppose each time to build a tree node.

under that can be expanded.

every time the loop runs it remember the last level of the node and instead of

initialing the tree, it starts from the last node it created.

I need a method that initialize the tree.

thanks
