Hi Luke,
Instead of trying to pull this information into a project report, you may want to consider building an issue report instead . . . . Following your example through, it looks something like this:
1) Initial request raised and converted into project 'A'
2) Issue created on project 'A'
3) Issue on project 'A' is converted into another project 'B'
Using an issue report you could then add the following columns to your view:
Issue >> Name - The name of the issue that was created on project 'A'
Project >> Name - The name of project 'A' where the issue was created
Resolve Project >> Name - The name of project 'B' in my example above
Would that work for you?
Best Regards,
Rich.
