Limitations

  1. Qlik Cloud API Usage

    The connector uses the Qlik Cloud API to catalog data sources (QVDs, files, and datasets) and to establish their lineage relationships with tables and table columns. The connector does not use this API to catalog Qlik Cloud as a primary BI source.

  2. Cross-System Lineage Not Supported

    The connector does not currently support cross-system lineage due to Engine and Cloud Lineage API limitations.

  3. Column Name Mapping

    Some sheet columns may map to multiple table columns when identical column names exist across different tables. Qlik Sense combines values for all fields with the same name, so lineage will be represented in one-to-many mapping

  4. Incomplete Representation of Transformation Logic

    The lineage does not fully reflect certain Qlik transformation logic due to:

    • Limitations in the available Engine or Cloud APIs.

    • Missing or incomplete field-level mapping details from Qlik Sense in specific scenarios.

  5. Reduced Lineage When Cloud Lineage Is Disabled

    When Cloud Lineage is disabled, data source (QVD, file, and dataset) to table mappings are not created. In this mode, data sources are cataloged from the Engine API response, which results in reduced lineage information.

  6. Master Items Not Linked

    Master items do not link to their upstream sources or tables.
