If you try to record a transaction that would result in zero units on hand, you might receive the following error. This means that while your inventory quantity will be zero, the value of the items you're adjusting would not return to zero.
That error message is a very common message in MYOB.
When converting Purchase Order to Bill comes up with Alert :
Items on Purchase Order:
Qty 100 with value $1000
MYOB Inventory card shows:
Qty 100 with value $1000.70
MYOB does not allow a qty 0 unit balance with balance of $0.70
Before you can record the transaction, you need to adjust your inventory value by the amount that it's unbalanced by.
