Parked Documents in CO reporting

[Cooper, Tom]

Hi All
 
Is it possible to include values from parked documents into CO reporting?
 
I am using SAP delivered libraries for Project (WBS element) reporting.  The
libraries use table CCSS.
 
When constructing report elements, it is possible to separate data by field
WRTTP - value type.    There is a value type "60" for parked documents.
 
I cannot find where there is any data stored for value type 60.
 
I see that parked documents create entries in FI in tables VBKPF, VBSEGA,
VBSEGD, VBSEGK, VBSEGS.  I do not see where a CO document is created at that
time.  However, if no CO document is created, then what would be the use for
a value type of '60 - Parked documents'?
 
Any direction would be appreciated.
