I received units of an item but the system is showing more consumed than that. Why would it show different quantities?
If the stock is showing more consumed than received quantity then it is because you have allowed for generating the voucher even if there is negative stock. For checking the configuration of Negative stock you can refer to the steps as below :
1. Go to Administration
2. Click on Configuration
3. Click on Warning alarm
4. From here check that you have either set No Action or Warning only Negative stock instead of Don't allow.
