Carry out this task

  1. Create or open the Before record on the linked tool.
  2. Save the lower remainder before rebuilding the QR.
  3. Check the saved After values before downloading the rebuilt label. Replace the older physical label.

Calculation and observed tool result

Before

1 × 1500 + 700 = 2,200 g

Recorded quantity: 2,200 g.

After

1 × 1500 + 500 = 2,000 g

Recorded quantity: 2,000 g.

What the result means

The new snapshot carries 2,000 g instead of 2,200 g.

Limits of this example

Separate devices retain older snapshots until labels are replaced.

A mistake to avoid

Rebuilding an unsaved form is blocked to prevent a misleading label.
