QlikView documentation and resources.
Returns the number of dimension columns that have non-aggregation content. i.e. do not contain partial sums or collapsed aggregates.
A typical use is in attribute expressions, when you want to apply different cell formatting depending on aggregation level of data.
This function is only available in charts. For all chart types except pivot table it will return the number of dimensions in all rows except the total, which will be 0.
What does it mean?
We have Table with 4 dimensions(columns): Product,Category,Type,Sales
Now we want to create Pivot Table by using those Dimensions.
We are going to use only 3 of them(Product,Category,Type) and use 4th(Sales) in our expression.
The result is shown below:
This Pivot Table has 3 dimensions so its maximum dimensionality is 3.
For better understating please see table below.
The function is used to show on which dimensionality level each of the Pivot Table row is:
'Sugar' has dimensionality of 1 which is Total for that 'Product'.
'Salt' has dimensionality of 2 which is Total for each 'Category' of that 'Product'.
'Oil' has dimensionality of 3 which is single value for each 'Type' of the 'Product's' 'Category'.
So then more Dimension we use the greater dimensionality of our Pivot Table is.
1) To show the level of dimensionality:
if(Dimensionality()=1 ,RGB(151,255,255),if(Dimensionality()=2 ,RGB(0,238,0),if(Dimensionality()=3,RGB(255,130,171))))
2) Highlight background of rows which on each level fall into certain condition:
if(Dimensionality()=1 and sum(Sales)<150,RGB(151,255,255),if(Dimensionality()=2 and sum(Sales)<=20,RGB(0,238,0),if(Dimensionality()=3 and Sum(Sales)<=20,RGB(255,130,171))))
Otherwise you will need to make changes the this path - [Dimensionality.xlsx]
(ooxml, embedded labels, table is Sheet1);

Are you referring to this table?
Sugar is the only column (dimension)in this section.
In Qlik Dimension=Column
yes this table
So have I answered your question as you wanted?
Very helpful post! Can you also explain the difference between Dimensionality and the SecondaryDimensionality and specific usage of the same! Thanks in advance!
Secondary Dimensionality is being used for Horizontal dimensions
The second dimension... or how to use secondarydimensionality()
Still feeling Qlikngry?

Very nice... (y)
Is there a way the sub totals for the different dimensions get there name before the "total" label.
Like Product Total
Practical post that I would recommend reading for everybody.
