Transactions Closing and Settling

We have thousands of records both in Inventsum and Inventtrans that have not and seemingly will not settle and close. There is not any inventory on these records but they do have a typically small financial value remaining on them. I and trying to determine how do I get these records to settle and close. We have inventory dimensions turned on to the pallet and serial number level. When I look at the onhand screen I have pages and pages of pallets listed with no qty. My record counts in inventsum are 461000 open and 42000 closed. Anybody have any ideas on how to get these records closed and what may be causing this? We close inventory monthly and perform weekly cost recalculations. I am also curious which transactions type in inventtrans should eventually close? All of them? Some of them?

We have a similar issue. Did you ever come up with a solution for this?
