Regarding refreshing tree

[surya_ramireddy]

Hi Experts.

There are two screens namely 100 and 200.. Screen 100 contains selections and based on selections i am displaying screen 200 with tree structure.. Now its displaying exact results.

When i come back from screen 200 and changed the selection paramters in screen 100. If i go to screen 200, its still displaying the same screen with the old values.

Can you tell me how can i go farward ?

Regards,

surya.

Hi ,

While returning screen 100 use FREE method of alv tree instance and also you can try FREE : gi_tree.

Hello Surya

It is always the same problem:

How can you expect a reasonable answer if your question is missing any kind of details???

Searching classes with CL*TREE you will find on ERP 6.0 more than 300 different one.

Assuming that you are using CL_GUI_ALV_TREE the required method calls would be:

(1) DELETE_ALL_NODES
(2) Build the new tree using methods like ADD_NODE
(3) Update the display using UPDATE_CALCULATIONS

CL_GUI_SIMPLE_TREE:

(1) DELETE_ALL_NODES
(2) Build the new tree using methods like ADD_NODES
