Which ESR field is the work order number?

• A. It is the serial number (S/N)
• B. It is the date/time
• C. It is the work order number (Order No.)
• D. It is the 9-digit NIIN

Answer: (C)

The work order number is placed in the field labeled Order No. This field is designated to track the maintenance or repair task tied to an asset, giving you a unique reference for that job. The serial number identifies the specific asset itself, not the task. The date/time records when actions occurred, and the 9-digit NIIN identifies the item in inventory, not the work order. So the correct placement for the work order reference is the Order No. field.
