AJO datasets, delivery and tracking data (feedback, journey step events datasets etc.), are available in AEP automatically. Adobe Campaign datasets can be imported into AEP for campaign delivery and tracking data using the AEP Adobe Campaign source connection.
Once the datasets are available in AEP, create a connection using CJA with the required datasets (AJO+ACC).
Once the connection is ready, create a data view with necessary metrics and dimensions by selecting the required columns from the AJO/ACC datasets.
Once the data view is ready, create a project from the data view created above, which holds ACC and AJO data. This will help analyze KPIs of ACC and AJO.
Please refer to https://experienceleague.adobe.com/docs/journey-optimizer/using/reporting/cja-ajo.html?lang=en for a demonstration on how to analyze AJO data in CJA. Import ACC data into AEP, utilize it in CJA along with AJO data, and create different visualizations according to the AJO-journey and ACC-Campaign.
