Carry out this task

  1. Create or open the Before record on the linked tool.
  2. Save the pour-adjusted remainder, rebuild and attach the newer QR.
  3. Check the saved After values before downloading the rebuilt label. Replace the older physical label.

Calculation and observed tool result

Before

1 bottles × 750 ml + 400 ml = 1,150 ml

Recorded quantity: 1,150 ml.

After

1 bottles × 750 ml + 250 ml = 1,000 ml

Recorded quantity: 1,000 ml.

What the result means

The new label represents 1,000 ml instead of 1,150 ml.

Limits of this example

Stock outside this bottle record is not included in either snapshot.

A mistake to avoid

Rebuilding before saving would intentionally use the older saved amount.
