ALV tree - change node text

Posted on Nov 23, 2005 at 01:50 PM 269 Views

hello,

on a screen I have input fields such as year and below a container holding an ALV tree.

When I change the year value, that starts a new selection from a table and should result in changing many of the lines in the tree.

I was trying to use the methods "get_outtab_line" to retrieve the tree line data and then changing this data with method "change_node".

The problem is I cannot access the correct node-key. The node-key value is kept in memory somewhere and when I refresh the alv tree at PBO, the node-key is incremented from the stored value which means I cannot use get_outtab_line properly.

Any suggestions or example programs,

Thanks a lot,

Kevin

    Hi Kevin,

    Here is one approach that might work actually,

    Use get_top_node method of ALV Tree to get the top node key every time you refresh and then add this to the node key that you have already stored before calling get_outtab_line.

    Hope this helps..
