Manufacture process

In manufacturing process Total Outgoing Value (Consumption) and Total Incoming Value (Receipt) are same But higher amount post to Cost of sales . What’s is the error

Please give me more info to work with.

By consumption and receipt are you referring to the purchase price of raw materials and the sales price of the FG?

If you say that both of those values are the same, then does that mean you don’t have any operations mapped to the BOM for creating that FG?

Did you have any process loss in the work order for that particular batch? As this would affect the value of the FG.
