Hello @Gloria,

there is an Audit log that you can use for such information. https://docs.ataccama.com/one/latest/audit/audit.html To make these statistics, it might be better to use the API: https://docs.ataccama.com/one/latest/one-apis/audit-api.html and aggregate the different logs. Ataccama logs everything and it might be overwhelming.

There is a comment under this article with an example of IDE plan extracting such data from the Audit log:

Also, by default the audit log is enabled only on source and Catalog items. If you want it also for other entities, you need to turn it on using a trait audit:auditEnabled (see the above documentation).

Let me know if this helps.

Kind regards,

Anna
