DrillUp in Extensions

[#1]

Hi,

JS Api for Extensions hs the following description for "DrillUp":

-----------------------------------------

{void}DrillUp(steps, colNo)

Note! Only available for Extensions.

Parameters:

steps

colNo

------------------------------------------

Guessing here, I passed 1 for "steps" and Column Number for "colNo", with neither effect, nor error.

My expectation is that it will drill up a "drill-down group".

What am I doing wrong?

My QlikView version is 11.2

Thanks and Happy New Year,
