- Flows
  This documentation describes how Flows can be run from REST API, listeners, or they can be scheduled.
- Maps
  Maps define input and output specifications and mapping rules for data transformation.
  - Using Maps
  - Create maps to specify sources and targets
  - Maps and map source files
    Basic tasks involved in creating and managing maps.
  - Input and output cards
  - Card settings
  - Map rules
  - Formulating map rules
    - When input data is missing
    - Mapping an input item to an output item
    - Mapping a group to a group
      - Automatic conversion of syntax items
      - Mapping to a group with a maximum range of 1
    - Outputs with maximum range greater than 1
    - Indexing an output
      When you know the number of objects to generate for each map execution, index the number of occurrences of that output object. To index an output is to generate a specific number of occurrences of that output.

- Schemas
  Use the schema designer to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
- Connections and Actions
  This documentation describes connections and actions.
- Files
  Files are used in various places within HCL Link. HCL Link allows files to be uploaded to the HCL Linkserver.

Mapping a group to a group

Desired output of an input group may be the same as an input group. If the output group is the same type and is defined in the same schema as the input group, drag the input group into the map rule cell of the output group. If the input group is a partition of the output group, you can drag the partition into the rule cell of the output group.

If the input group and output group are different types, you cannot drag the input group to the output group. Either expand the output group down to its item components, or use a functional map.
