How to map Cost Management resource transaction to a specific Project Resource in PFM

Summary:

When transferring Actual Cost Collection from Supply Chain Cost Management to Projects, I would like to map each Cost Management resource transaction to a specific Project Resource in PFM.

However, I’m not sure which setup controls this mapping.

Example Scenario
In Cost Management, suppose I define the following Cost Elements:
Labor A
Labor B
Labor C
In Projects, I would like the actual cost collected to map as follows:
Cost Element (SCM) Project Resource (PFM)
Labor A Labor Costs
Labor B Fees
Labor C Services
Question

What setup is required in Project Financial Management to map SCM Cost resource transactions (Cost Elements) to specific Project Resources when performing Actual Cost Collection?
