Ingest an object-centric event log

To access OCPM (object-centric process mining) in Power Automate Process Mining, first create a process model by ingesting the object-centric event log (OCEL).

To prepare the OCEL, follow the guidelines in How to create an object‑centric event log (OCEL). Then, store the resulting file in a CSV format in either Azure Data Lake Gen2 or OneLake.

Ingest the data

  1. On the navigation pane to the left, select Process mining > Start here.

  2. Select Object-centric process mining.

  3. In the Process name field, enter a name for your process.

  4. Under the Data source heading, select Azure Data Lake or OneLake and select Continue.

  5. In the Choose where to export step, select Continue to set up the export of OCPM semantic model in your Fabric workspace, or Skip export.

  6. To set up the Fabric workspace:

    1. Select from the list of available Fabric workspaces.
    2. Select a Fabric Lakehouse in the workspace.
    3. Select a name for the default report that will be created for the resulting semantic model.

    Learn more in Export OCPM semantic model into Fabric workspace (preview).

  7. The subsequent steps on the Connection setup screen differ for Azure Data Lake or OneLake. Follow the respective documentation until you reach the attribute mapping screen:

  8. On the Map your data screen, map your data columns to appropriate attributes.

    • You must map one attribute of type Activity.
    • You must map one attribute of type Start event.
    • End event attribute is optional.
    • Resource attribute is optional.
    • You must map at least two attributes of type Object type.
    • Event and Object level attributes (including financial) are optional but highly recommended for more detailed analysis

      • An event level attribute is bound to the event itself, so even if the event references several objects of different object types, the attribute is bound to the event in all of the referenced objects.

      • An object level attribute is bound to the object of a particular referenced object type. The value is taken from the last or first event referencing that object type. To define the object level attribute, first select the Object Level Attribute (first or last event). Then, in the selection next to it, select the Object type to which the object level attribute is connected.

  9. Select Save and Analyze.

    After the ingestion finishes, you're navigated to the process intelligence experience for OCPM with the Process overview tab active.
