We have a item, when I check the on-hand, the quantity is zero, however, the finacial cost is 978.2. How can I remove this balance? I use the Profit & Loss journal, I put in cost amount = -978.2. After posting, the cost is becoming 102.1. I check the voucher of the journal, the cost amount is actually -876.1, not -978.2. How could that happened?
