CRM 2011: How to update 'Modified By' field of closed case

Question

I have a workflow which automatically close the case after 7 days. But because it resolved by a workflow, Case's Last Modified By field is set to process owner. For reporting I want to set the Last Modified By equal to Case owner.

Is there any way to do this?

I think CRm don't let us to update closed case so I can't do this with post-operation plugin.

Thanks

Answer 1

My suggestion is to add a boolean field inside the case entity such as "Case Closed Automatically" and set it to true when the case is closed by the workflow.

In this way inside the report you can show the actual Modified By value for the cases closed manually, and the case owner for the cases closed automatically.

I know it's not the right answer, but it's easier to implement than a plugin or something else.
