First Subset

Contents[Hide]

The First Subset function returns a specified number of values that appear first in an input data series. For example, the function can be used to return the first 3 values.

1. Syntax

FIRST(d0,s0,Alignment)

2. Input

The First Subset function requires the following input:

  • d0 - Input data values - The set of data values for which the First Subset is calculated.
  • Alignment (Optional) - A hierarchy placeholder to be used as the alignment axis.

3. Parameters

The First Subset function requires the following parameter.

  • s0 - First Subset Count - The number of values to be returned by the formula. Default value is 1.

When you use the FIRST function within a metric set, it can only return a single value (s0 must be 1). In order to return the first 3 values, for example, you must use a formula visualization. This applies to the other subset functions as well.

4. Output

The First Subset function generates the following output:

  • First Subset - The First Subset result set.
