Hi @jm_11,
The Profile Snapshot dataset is available in AEP. Another dataset that AJO writes is - AJO push profile dataset.
Below is the list of all the automatically created dataset that is used by AJO (available in AEP):

To create a report in CJA on a Profile attribute to see the trend of updates (from value AAA to BBB), there are 2 ways:
Option 1- Run/Schedule a daily Query Service job in AEP that takes the daily exported data from the Profile Snapshot Dataset and convert each profile value into time-series data, then insert that into a separate dataset and then uses this dataset in the CJA connection.
The Profile Snapshot Dataset mentioned above is available in AEP which gets refreshed daily with the latest Profile data ingested in Individual Profile Datasets.
Option 2- When the data is ingested in AEP for an Individual Profile Dataset, ingest the same data using another dataflow to a time series dataset (Experience Event) along with a timestamp value i.e. ingestion time.
This Experience Event dataset should not be enabled for profile. When you use this dataset in the CJA connection, you will see the previous values for all the profile attribute.
Hi @kumar29917170hcyp
Can you please confirm that adhoc created datasets from Query Service will show up as potential datasets to add in a connection.
I created 2 datasets using the CTA functionality in query service, yet they were not showing up as datasets that I could add to the connection. Please let me know.
