Tree visualization

Former Member — Thu, 26 Jan 2006 15:51:49 GMT

I have to draw a tree which can be printed.

For example I have a material A. This is splitted in three other materials B, C and D. Material B is splitted in material E and F. Material D is splitted in G and H, and so on.

I have to visualize such a tree. The number of childs for each node in each level of the three can be different for different materials.

Has SAP a tool which can be used for this?

Hi Frank,

you could use class CL_GUI_SIMPLE_TREE (look at sample program SAPSIMPLE_TREE_CONTROL_DEMO) or CL_GUI_ALV_TREE.

look also at those sample reports:

BCALV_TREE_01

BCALV_TREE_02

BCALV_TREE_03

BCALV_TREE_04

BCALV_TREE_05

BCALV_TREE_06

BCALV_TREE_DEMO

Kind regards, Manuel

I think you should look at 'SAP graphics'.

This should fit to your requirements.

Have a look at sample programs:


GRHIER_1
BCGRDEMO

They use FM GRAPH_HIERARCHY_MENUE and display hierarchy structures.

I tried to solve the problem by calling the function "GRAPH_HIERARCHY_MENUE" which has been used in the program BCGRDEMO.

The only problem I have is that when a child has two different parents, this child is painted twice (once for each parent). This child has to be painted only once with a relation to the two different parents.
