Carry out this task

  1. Save the Before values on the linked tool.
  2. Subtract the measured transfer from the open remainder.
  3. 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 × 500 ml + 350 ml = 850 ml

Recorded quantity: 850 ml.

After

1 bottles × 500 ml + 150 ml = 650 ml

Recorded quantity: 650 ml.

What the result means

The shelf record decreases by 200 ml.

Limits of this example

A transfer is not necessarily household consumption.

A mistake to avoid

Keeping transferred liquid in the refill record duplicates it if the dispenser is tracked.
