Hi,

We are using sales, accounting, Purchases and Warehouse modules in the OpenERP 7. We saw sudden changes in the quantities of the products in the inventory. When tried looking at logs of these changes, no relevent logs found. This change has happened for about 70% of the inventory items, not all. The quantity changed are different for each product. 

Additionally, there are rate change happening for some products sometimes (not regularly), and a few new columns (expiring in 30 days, 30-60 days, 60-90 days etc) started appearing on the serial number page. 

We are not able to understand the issue and investigate it further. Is there a way to investigate such an issue. Any guidance / support in this regard will be superuseful.
