How to update oOrder and oInvoice Items' COGM?

Question

I am attempting to update the COGM and Profit Margin values for Non-Stock items when an associated Purchase Invoice for these non-stock items is received.  This is being done to have more accurate booked order and invoiced order reports.  The code I have written is shown below.  As yet, I am unable to find a way to reach the RDR1.GrossBuyPr column (labled as COGM in the UI) and INV1.GrossBuyPr column (also, COGM in the UI) from the DI API.  Is there another way to update these values.  Also, how would I update the Profit Margin for the respective lines?
Any help would be greatly appreciated!

Hey Scott.  There is no COGM property.  You have to update the table directly.
