The order probability of 30% is the default value that was set for GBI for inquiry documents. The expected order value is then 0.30 x 21,400.00 = 6,420.00. We can change the order probability for an inquiry, which makes sense as different customer inquiries would have different probabilities of becoming an actual sales order.
Change the order probabilities to 70%, then click on the enter icon to update the inquiry and note the new Expect.ord.val of 14,980.00.
