Release Notes 1.20.425​

Managed App Version: 1.20.425

New Features​

SAP OData Extraction Support​

dab Nexus now supports data extraction from SAP systems via OData in addition to the existing RFC-based extraction. When creating SAP connections in Settings, you can select between RFC and OData connection types. OData connections require a Base URL and support authentication via username/password or client certificate. OData connections follow the existing SAP system licensing model — each connection consumes one SAP system connection slot. No additional licensing is required unless all available connection slots are consumed.

In Package Studio, OData packages display SAP CDS Views as tables and indicate CDC capability. Repositories, Reports, and Real-Time Objects are hidden for OData packages as they are not applicable to this connection type. A new hierarchical table selection component handles OData's structure of Service Groups, Services, Service Versions, and Entity Sets. Table names for OData now use the relative URL to the EntitySet (e.g., /sap/opu/odata4/sap/cdi_cds/cdi_cds/sap/i_companycode/0001/MasterData), which matches the documentation on api.sap.com.

In Extraction and Replication tasks, the connection type is determined by the first selected SAP system. When an OData system is selected first, only other OData systems and OData-compatible packages can be added. Data Masking, NEXUS_ID, and String Trimming options remain visible but are disabled for OData tasks. CDC for OData uses delta tokens and the existing scheduling mechanism.

Nexus API​

dab Nexus provides a public REST API for external automation and integration. The API exposes resources for Workspaces, Tasks, Runs, Parameters, and referenceable object types. Supported actions include creating, updating, starting, activating, deactivating, cancelling, and deleting resources. The API is fully usable without the dab Nexus UI and is documented via a specification.

New Task View for Real-Time Tasks​

Analytic, Extraction, and Replication tasks with Real-Time scheduling now display a new view instead of the previous list of individual runs. This view lists all tables for which data is transferred within the task, showing the number of extracted or changed records, the timestamp of the last successful update, and the record count from the most recent execution. Clicking a table opens a detail view with a summary of the initial full load and a chronological list of delta increments. Tasks without Real-Time scheduling retain the existing run list.

Localization​

dab Nexus now supports German as an additional language. Users can change the language in their profile settings. Language preferences are stored per user.

Improvements​

  • Run history in the task view now uses a table layout instead of the previous row-based display.
  • Package import validates the package type and shows only compatible SAP system types in the selection dialog.
  • Package Editor received a wave of updates and improvements
  • Character limits for table aliases and other naming elements in Package Studio have been extended to 50 characters.#273874
  • Error messages for invalid packages now reference the problematic object rather than internal file paths.
  • Packages now support DateTime input types for timestamp filters that contain date and time values.
  • Exception messages from inner exceptions are now displayed in error dialogs for better troubleshooting.
