Argument
Required/Optional
Description
string
Required
Input port name.
group by
Required
Name of the input port that contains the group identifier.

Return Value

The most frequently occurring value, including blank or null values.
If the highest number of occurences is shared by two or more values, the strategy returns the first qualifying value.

Example

The following expression uses the
CONSOL_MOSTFREQ
function to analyze the Company input port and find the most frequently occurring value:
Company1:= CONSOL_MOSTFREQ(Company, GroupKey)
In this expression, the
CONSOL_MOSTFREQ
function uses the GroupKey port to identify a record group. Within that record group, the function analyzes the Company port and returns the most frequently occurring value. The expression writes this value to the Company1 output port.
