Group Key Generator

Group Key Generator is used to transitively merge the selected fields. The value of transitive merged fields appear as a new field specified in the Generated Group Field. It uses a grouping strategy to create group keys for the selected fields that you want to transitively merge.

For example, use this stage to transitively merge results in a multi-match scenario, where the output of multiple Intraflow stages (performed matching on different keys and rules) can be transitively merged.

Note: Make sure that the field Assign collection number 0 to unique records in the Intraflow stage is disabled.
