In Alma it's not possible to use the adv search bar/jobs/analytics to list records from external data sources. We can see the records loaded in the History option of each profile execution. But to have a total, we would need to open one by one.

Could it be possible to have the amount of records and MMS IDs of each discovery import profile available to see?

For example, in the same menu list where we see the History, Reload and Delete, etc, add an option called: Total and when we click on it Alma searches for all records of the data source and displays the MMS ID.
