Your understanding is too strong. Must lose weight. Otherwise, the efficiency and practical significance are relatively poor. Performance will also be very low.

When standard cost >: allocation cost, standard cost = allocation cost. Is this an update? Or a request? Write you a token:

Select the first two columns you choose, and standard cost = what happens when standard cost > allocate cost, otherwise, standard cost ends and allocate cost.

Starting with XXXXXXXXXX
