Carry out this task

  1. Create or open the Before record on the linked tool.
  2. Save the reduced remainder, rebuild and replace the shelf label.
  3. Check the saved After values before downloading the rebuilt label. Replace the older physical label.

Calculation and observed tool result

Before

Stock = 1 × 1000 + 400 = 1,400 g; floor(1,400 ÷ 200) = 7 refills

Recorded quantity: 1,400 g.

After

Stock = 1 × 1000 + 200 = 1,200 g; floor(1,200 ÷ 200) = 6 refills

Recorded quantity: 1,200 g.

What the result means

The updated snapshot represents six full refills instead of seven.

Limits of this example

A replacement label cannot revoke previously copied snapshots.

A mistake to avoid

An old PNG still carries the previous open-stock amount.
