Project Systems Retraction

I have been successful in getting or retraction to work for Cost Center planning.

I would like to now use retraction to bring back project systems information. My question is - Is there a way to bring back Depreciation Simulation Data into R/3 visible in transaction CJ20N. (The menu path in R/3 is CJ20N > Edit > WBS Element > Investment Programs > Depreciation Simulation data.)

In other threads I can see that you can retract back to PS, but I do not see what fields you can retract back and what tables are being populated.

Thanks in advance for your reply.
