I was trying to get a report created for Case Approval History. Followed Create a Custom Report Type for Approval History
But it doesn't have lookup to objects that we need for reporting.
I need to get Case detail fields, and Account fields to group by for the report.
I did go through path to see if we can add custom lookup,etc. to ProcessInstance object
But it seems not possible.
Is this possible to do with a workaround?
What would be the easiest way to get a report preferrably with least coding involved?
