Fields can be combined into a new dimension by creating a Group.
Groups are used to combine different dimension values. Once grouped, these values show up as a new dimension field under Dimensions. Group is also used to improve data quality in a dashboard. For eg., if visualization contains values such as Unites States, USA, US, you can combine all these values into one Group and have a value like the USA.
