I have a task to organize an ability to change element's parent from one to another without using Modeller.

I was trying PALO.EUPDATE function, but it seems, that it doesn't work for me.

For Example I have the following heirarchy:

-In progress

---task 1

---task 2

-Completed

---task 3

---task 4

And I need to move 'task 2' under 'Completed' without using Modeller.

Do you have any ideas?

Thank you for any help.
