Skewness's definition:

Skewness is a measure of symmetry, or more precisely, the lack of symmetry. A distribution, or data set, is symmetric if it looks the same to the left and right of the center point.

In context of QlikView I may not have a sample readily available. But this is a statistics concept related to Normal Distribution where a 0 skewed data will have Mean = Median = Mode. But a negatively or positively skewed data will not have them equal. Have a look at the image below
