Group
Replace multiple values with a single value (constant or calculated).
Use cases
- Creating flags that can later be used in expressions. In this case the flag will designate a group (set), therefore verifying if a value belongs to the group can be done by checking the flag.
- Group values for charts (e.g. changing insignificant dimension values to "Other")
- Calculating new values of a column only for particular values in another column, leaving the rest unchanged.
