- Calculate & Save the After values on the same item. Check the ID is retained rather than creating another physical item.
Calculation and observed tool result
Before
1 bottles × 1000 ml + 600 ml = 1,600 mlRecorded quantity: 1,600 ml.
After
1 bottles × 1000 ml + 350 ml = 1,350 mlRecorded quantity: 1,350 ml.
What the result means
The shelf record falls by 250 ml; a separate dispenser record is optional.
Limits of this example
The tool does not measure the dispenser automatically.
A mistake to avoid
Counting transferred liquid in both records would duplicate it.
