Availability of the column "Outline number" in the Resources Chart

In the current version the column “Outline number” is not available in the Resources Chart.
The Outline number is very helpful to identify each entry in the structured plan.

I was not able to add this column via “Manage Columns” on the “Resources Chart” tab.

Outline number is a property of a task, it doesn’t make too much sense for the resources. If you meant to say that you need to identify tasks under the resource nodes, you can use ID column, which shows the ids of the assigned tasks.

Hello Dimitry the Outline number is the Identifier in the structured plan (PSP).
It is quite helpful to identify an entry (PSE) in the structured plan.

So what is your goal? Do you need a way to identify a task under a resource node or something else?
