Carry out this task

  1. Save the Before values on the linked tool.
  2. Remove one full refill from the record.
  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

2 × 150 + 25 = 325 sheets

Recorded quantity: 325 sheets.

After

1 × 150 + 25 = 175 sheets

Recorded quantity: 175 sheets.

What the result means

The correction removes 150 sheets while retaining twenty-five open sheets.

Limits of this example

Physical inspection determines which component needs correction.

A mistake to avoid

Do not erase the open box merely because another box is empty.
