We only have 8 products on the system. Every time I carry out a stock adjustment for two of the items, the QOH is out by 1. For example - we had 1 item left in stock. Today we produced another 43. I updated the stock levels using stock adjustment and would expect the QOH to now show 44 - the physical amount we have in stock. Instead the value reads 43. We don't have any invoices on the system with a future date that could be effecting the QOH - any ideas what could be causing the discrepancy?
