Post inventory cost to G/L, report 1002

TheoK

Hi,
our customer has been posting purchase invoices for a while, without Automatic Cost Posting activated, and never ran the report 1002 Post inventory cost to G/L. Now we need to run it but we don't want G/L postings in the previous year.
I've been testing with the Allow Posting From date and Inventory/Accounting periods, but I think that only effects the Adjust Cost Item Entries batch, not the Post inventory Cost to G/L.
Is there a way to have last years posted invoices, posted to G/L in 2011?
Thanks!
