Hello, is there any way to show "Spent Time" inside "Cost Report" from work packages of a project that was archived?

We would really need this feature as well. Sometimes you want to evaluate times spent on past projects over the years as compared to current projects, but none of the times spend in archived projects are considered in cost reports. I'll write a feature request.

Thank you very much for leaving your comment in feature request OP-6788. 

Have a great day, 
Samantha
