deleteNode()

deleteNode() is used to delete nodes when the dialog works with a tree table. You can fill the program array before the dialog execution using BEFORE DISPLAY and BEFORE DIALOG control blocks.

The method needs two arguments:

CALL DIALOG.DeleteNode("screen_array", index)

screen_array	passes the name of the screen array identifying the tree
index	specifies the index of the node that should be deleted from the program array

Unlike deleteRow(), deleteNode() deletes all child nodes and only after that removes the node identified by the index argument.
