QlikView Rank Functions

QlikView provides a set of Rank functions that allow users to determine the relative position of values within a data set. These functions are useful for identifying top or bottom values or for creating rankings or leaderboards.

Here are some common rank functions in QlikView:

• Rank(): This function returns the Rank of a value within a data set based on a specific expression or dimension. The Rank () function, for instance, can be used to find the rank of sales within a set of data.
• Rank() Over(): This function returns the Rank of a value within a data set based on a specific expression or dimension and allows you to specify the window or partition over which the ranking is performed.
• FirstSortedValue(): This function returns the first value in a data set based on a specific expression or dimension after the data has been sorted in a particular order.
• LastSortedValue(): This function returns the last value in a data set based on a specific expression or dimension after the data has been sorted in a particular order.

You can use these rank functions in QlikView to create rankings, leaderboards, and other types of data visualizations that show the relative position of values within a data set. To develop more complex calculations and analyses, you can combine them with other functions and expressions.

In QlikView, the “Rank” function is used to assign a rank to a field based on its values. The function returns a new field that contains a ranking of the values in the original field. The ranking can be based on the values in the field in ascending or descending order.

For example:

scssCopy code
=Rank(sales)

This will create a new field with a ranking of the sales values, in ascending order.

Another example:

scssCopy code
=Rank(sales,0,1)

This will create a new field with a ranking of the sales values, in descending order.

This function can be used in combination with other functions such as “Aggr” and “Group By” for more complex ranking.

For example:

lessCopy code
=Rank(Aggr(Sum(sales), category))

This will create a new field with a ranking of the sum of sales values, grouped by category, in ascending order.

The “Rank” function is useful for identifying the relative position of a value in a field, and can be used to create visualizations such as bar charts, line charts, etc. that show the ranking of different values.
