An invented quantity difference

Lot A opens at 200, adds 100, and records 80 used. Expected closing quantity is 220. A count of 218 leaves a difference of minus 2.

Investigate before correcting the holding

Use the balance calculator for arithmetic. Investigate a difference before changing the recorded holding. The worksheet cannot count physical stock.
