I assume CoGS = Cost of goods sold. This is the same as Cost of sale. COGM is, I assume, cost of goods made. There are two versions of that: Marginal cost: this includes only the variable cost of cost of the goods made. Total absorption cost: in addition to marginal cost, this includes the fixed production overheads. That is almost certainly what is meant by 'total production cost'.

Thank you... I really got the same concept.
