Carry out this task

  1. Save the Before values on the linked tool.
  2. Edit only First use date after checking 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

Start 2026-11-01 + 14 days = 2026-11-15. Follow product instructions and actual condition.

Recorded quantity: 2 items.

After

Start 2026-11-05 + 14 days = 2026-11-19. Follow product instructions and actual condition.

Recorded quantity: 2 items.

What the result means

The review moves from November 15 to November 19.

Limits of this example

Use the best available record rather than inventing an exact date.

A mistake to avoid

Changing the spare count cannot correct a mistaken start date.
