What is the bind variable that can be used for Maintenance Work Order Id in DFF SQL?

Hi,

While trying to fetch data automatically in the DFF, I'm not able to figure out the parameter segment for work_order_id. I'm trying to use the SQL code:

SELECT ATTRIBUTE_TIMESTAMP2 - ATTRIBUTE_TIMESTAMP1
FROM WIE_WORK_ORDERS_B
WHERE WORK_ORDER_ID = :{PARAMETER.WorkOrderId}

Kindly help.
