Potentially missing info from AH API

Hi all.

Using the API to get data from AH to pop it into Power BI for our reporting and I’ve been using it fine for ages, but another use wanted a report generated which included the “process_volumes_per_year value” - and it’s not there? 33 other “process_” data columns, but no volumes?

Is this the same for others? Is there a workaround?


EDIT: I can see this value in postman, but not in Power BI or Qlik either.
