Tree node click: We have customized transaction CJ20N with a GuiXT Script. What is missing is the possibility to capture a click on the upper tree control. There are two tree controls on the left hand side, and it seems that the On Enter control="..." does not work in this case.

We suggest that you save the value of the project number shown in CJ20N. When the user clicks on a different tree node the GuiXT script is executed and you can check whether the key value has changed.
