Tree structure format in report.

Former Member · ‎07-02-2007

Hi all,

I have got a report to develop where in i have to display the ouptut of the report

in a tree structure.Can anybody tell me how to proceed with this ?? This is

basically an interactive report where clicking on one of the node will take us to

another page.

Thanks and Regards.

Hi,

You can use tree custom controller to do that, or HTML controller in case of weblinks.

You can see all examples of it in SE38.

see BS* and press F4 , search for tree.

Reward if useful!

hi,

Does it mean that you have to do an ALV intearctive report and you have to use the function reuse_alv_hier_seq to display the nodes.

thanks

Hi,

You can use the classes CL_SIMPLE_TREE_MODEL or CL_GUI_ALV_TREE to achieve this. Please look a the example prog's in SLIS package for CL_GUI_ALV_TREE based tree & package SEU_TREE_MODEL for CL_SIMPLE_TREE_MODEL based trees.
