This action generates group numbers in a new column.

A "group" is defined by unique values in a column or unique combinations of values across multiple columns.

This action can be used to create group ID numbers for later reference, lookups, or merges.

Groups are enumerated starting from 1.

The new column containing the group numbers will be named "GroupNo" and appear as the leftmost column, by default.

When multiple columns are selected, the unique combinations of values across the selected columns constitute the "groups".

Enumerate groups based on the values in the "Province" column.

Column: Province

Generate group numbers from the values in the selected columns.
