Carry out this task

  1. Save the Before values on the linked tool.
  2. Reduce the cupboard remainder and create a kit record for the ten moved bags.
  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 × 20 + 15 = 35 bags

Recorded quantity: 35 bags.

After

1 × 20 + 5 = 25 bags

Recorded quantity: 25 bags.

What the result means

The cupboard decreases by ten; the household total need not decrease.

Limits of this example

Location transfers require two explicit record updates.

A mistake to avoid

Do not leave the transferred bags counted at both locations.
