Trace for general data
The trace file records map execution progress. You can enable the trace option from the map settings or from the adapter command line. You can trace the input data, the output data, or both.

- 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.

    - Trace files
      - Trace for general data
        The trace file records map execution progress. You can enable the trace option from the map settings or from the adapter command line. You can trace the input data, the output data, or both.
        Creating a trace file
        You specify the name and location of the trace file in the map settings. If you ran a map and got a message that an input was invalid, turn on the input trace only. If you got a message that an output was invalid, turn on the output trace only. If you trace both input and output, the input messages are at the beginning of the file, followed by the output messages.
        Trace file contents
        When data is valid
        Group validation
        Valid card objects
        Invalid data
        Invalid card objects
        Finding the important messages
        Existence of data
        Validation for invalid objects
        Unknown data
        Negative messages not fatal
        Example of optional occurrences
      - Static file validation and tracing
        HCL Link validates a static input file in a compiled map only once, when the map loads, and produces a trace file only if the static file fails validation.
      - Trace for XML data
      - Trace for XML parser errors only
  - Error and warning messages
- 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.

Negative messages not fatal

Sometimes validation of a given data object interprets the given data object as belonging to a type to which it does not really belong. In this situation, the data object will fail to belong to that type - but that is because the data does not belong.

In the following two situations, you may see messages that a data object fails to belong to a certain type because it is not really data of that type:

When an optional occurrence of a component that does not exist in the data is sought during validation
When an object of a partitioned type is sought during validation
