Integrity b/w Inventory & Accounts Ledger

Hello,

As part of running inventory & accounts ledger integrity process, when referring to accounts ledger inquiry program (p09200) to check the inventory control a/c (BS account) using a particular date range (e.g. 01/01/2010 - 31/12/2010), we found that amount shown in "YTD" & "Compulative" fields are not matched. On the other hand Inventory Ledger & Account Ledger integrity already worked out & there is no mismatch b/w them. Now my question why these amount are not same and what is the corrective action process to match these amount fields.

Thanks & Regards,
